John 3:1-17

¹ Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. ² This man came to Jesus by night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.” ³ Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” ⁴ Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?” ⁵ Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. ⁶ That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. ⁷ Do not marvel that I said to you, ‘You must be born again.’ ⁸ The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”

⁹ Nicodemus said to him, “How can these things be?” ¹⁰ Jesus answered him, “Are you the teacher of Israel and yet you do not understand these things? ¹¹ Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen, but you do not receive our testimony. ¹² If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? ¹³ No one has ascended into heaven except he who descended from heaven, the Son of Man. ¹⁴ And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, ¹⁵ that whoever believes in him may have eternal life.

¹⁶ “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. ¹⁷ For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.”

In the name of Jesus. Amen.

John 3:16 might be the most recognizable verse of all Scripture. It has, rightly, been called “the Gospel in a nutshell.” That being said, there is a common misconception about one little word of the verse – the word “so.” Most of the time, we understand “so” to mean “so much,” so we read into the verse, “God loved the world so much that He gave His only-begotten Son….” However, the Greek word that gets translated as “so” has a different nuance. It actually means, “in this way.” Here’s how it comes across in Greek, “For God loved the world in this way, that He gave His only-begotten Son, that whoever believes in Him should not perish but have eternal life.”

God the Father loved you by sending His only-begotten Son to die and rise again for you. It is one thing for a person to love you by sacrificing his own life for you. But your God goes further by giving His eternally beloved Son so that you might be saved through Him. In other words, if you ever have doubts about God’s love for you, you only need to look to the cross and empty tomb. By the concrete, historical, provable action of God sending Jesus to shed His blood, die, and rise again for you, God has loved you. That love has not, will not, and can not ever change.

In a lot of ways, that’s enough of a sermon right there, but you’re going to get more.

Today is Trinity Sunday. Scripture teaches that there is one God in three Persons and three Persons in one God. So, as Christians, we worship one God who is Father, Son, and Holy Spirit.

It’s easy for us as Christians to think that there is the God we know and love, but then there are a bunch of guys on the fringe of Christianity called “theologians.” These stuffy guys dress weirdly, have no social skills, and like talking about this thing called “the Trinity,” while go about the important things of real life. I hope this sermon is a beginning of seeing how doctrine – and specifically the doctrine of the Trinity – sparks a joy and wonder in our God who is Father, Son, and Holy Spirit.

The doctrine (or teaching) of the Trinity is the first mystery of the Christian faith. The doctrine of the Trinity is not a secret. A secret is something that you keep to yourself, and if you tell it to another person it isn’t a secret anymore. A mystery is something that, even if you say it and confess it, is still a mystery and above our comprehension.

Let’s start with a quick overview of the Trinity.

Even though the word “Trinity” is never used in Scripture, it is a concept that Scripture presents, so we believe, teach, and confess it. And the word “Trinity” is a helpful term that has been used by Christians going way back to the late 100’s AD. “Trinity” smashes two words together – tri meaning “three” and unity meaning “oneness.” This week, I came across how “Trinity” is communicated in sign language, and it is absolutely beautiful. You hold up three using your thumb, index, and middle finger on one hand behind your other hand; then, you move those fingers underneath and to the front of your other hand to hold up your single index finger.

First, let’s talk about the unity of the Trinity. In the Old Testament, God gave His people a creed to confess, and it opens like this, “Hear O Israel the Lord our God, the Lord is one” (Dt. 6:4). We Christians worship one God, yet the testimony of Scripture is that this one God is also three Persons.

The Trinity is taught in the opening chapter of the Bible (especially when we understand creation in light of the rest of the Scriptures). The very first verse of Scripture says, “In the beginning, God created the heavens and the earth.” The Hebrew word for “God” is אֱלֹהִים (Elohim) and is the most common Old Testament name for God. The interesting thing about the Hebrew word Elohim is that the word is plural in form, but throughout the Old Testament the verbs that follow Elohim are singular.

Also, at creation, you have God the Father creating, God the Holy Spirit hovering over the face of the waters, and God the Son being the Word of God that creates as it is spoken. Admittedly we only rightly understand this when we know what is taught in Jn. 1[:1-3, 14], “In the beginning was the Word, and the Word was with God, and the Word was God…. All things were made through Him, and without Him was not any thing made that was made…. And the Word became flesh and dwelt among us…” We also get to hear the Trinity having a conversation before the creation of Adam and Eve. God says (and listen to the pronouns), “Let us make man in our image, after our likeness” (Gen. 1:26). Then Scripture goes on to say (again listen to the numbers in the nouns and pronouns), “So Elohim (pl.) created man (sg.) in His (sg.) own image, in the image of Elohim (pl.) He (sg.) created him (sg.); male and female He created them (pl.)” (Gen 1:27).

This is an aside, but part of the way that mankind bears the image of God is to have more than one person of the same nature and essence. Humanity has a plurality – male and female. This is why so much of the current push to normalize transgenderism is demonic. There is no other way to say it. The transgender movement isn’t a just a rejection of the way God created a person with boy parts or girl parts. It’s also a rejection of the true God who is plurality in unity. On the one hand, I hope this gives us more compassion toward those who have been deceived by the transgender movement. And on the other hand, I hope it helps us recognize the wickedness of the satanic nature of those who promote transgenderism. As the Church, we need to start preparing ourselves now to welcome back those who have undergone hormone treatments and mutilating surgeries because many of them will eventually realize how they have been deceived. In the next five to twenty or so years, we Christians will need to be ready to give the Gospel in loving, kind ways. I know there is a lot to explore there, but we’ll leave that for another time.

Back to the Trinity.

Now, there are some who will say that the three Persons of the Trinity are simply different ways that the Bible will talk about God. In other words, they say that in the Old Testament, God is depicted as the Father, in the Gospels as the Son, and ever since as the Holy Spirit. This error was given a name, “modalism.” Modelists wrongly say that there is just one God and Father, Son, and Spirit are just different titles for that one God. However, that can’t be the case. Already, we have seen all three Persons in creation, but we also see all three Persons distinctly and individually show up at the Baptism of Jesus (Mt. 3:13-17; Mk. 1:9-11; and Lk. 3:21-22). There you have Jesus, the Son, in the Jordan River, the Holy Spirit descending on Jesus in the form of a dove, and God the Father saying, “This is My beloved Son in whom I am well pleased.”

Now, everything said so far is pretty basic, and you have hopefully heard all of that at some point in your life. But I wanted to review that before we take it a step further. Because it is only with a right understanding of the Trinity that Scripture beautifully teaches two essential, joyful, wonderful things. First, that God is love. And second, that God is just and merciful.

Scripture teaches that God is love (1 Jn. 4:8, 16), but that can only be true because of the Trinity. If God were one, He could not be love. Here’s how that works: God is eternal and has always existed. And for God to be love, there has to be an object of His love. If God were one, He could not have love as part of His essence. Love would not be essential to His being. A god who is one and not triune could think highly of himself, but that wouldn’t be love; it would be pride. But with the Trinity it is possible for God to be love. There is an eternal love of the Father for the Son and Spirit. A love of the Son for the Spirit and Father. And a love of the Spirit for the Father and Son. This perfect relationship of love has eternally existed in the one God who is Father, Son, and Holy Spirit.

So, in God Himself, there has always been an object of love. Islam and Judaism cannot say that love is essential to who God is because they do not confess the Trinity. Now after creation, that perfect, eternal love that has always existed between Father, Son, and Holy Spirit, that love flows from God to us, God’s creatures. God shares that love with us. And, again, we see this most clearly in God giving His Son to save and forgive us.

And because God is love, the blessed Trinity can be merciful and just to forgive us and cleanse us from all unrighteousness.

I’m going to pick on Islam to make this point. The false god of Islam is Allah, and the Koran radically teaches that Allah is one. In fact, the Koran intentionally makes fun of Christianity for teaching that the true God is Triune. But again, a god who is one cannot have love as part of his essence. So, for Muslims, Allah has always existed from all eternity, but he existed as a solitary being and cannot have love as part of his essence. A false god like Allah can only be just; he cannot be merciful and loving toward sinners. In short, if god were only one, the story of that one god and his creatures is the story of an all-powerful master with naughty slaves. Maybe that false god could get his slaves back into his service, but he cannot love his slaves and they certainly cannot be his children.

But the true God is Triune. That means that God is perfectly just, but He is also merciful. Because God is Triune, God can provide Himself the sacrifice for sin as Abraham tells Isaac in Gen. 22:8. Salvation can only be by grace if God is Triune. If anyone but God Himself had to provide the sacrifice and satisfaction for sin, first, it wouldn’t be enough – it would not be sufficient. And second, it wouldn’t be by grace.

And if the Holy Spirit were not God, what possible right would He have to bring us into a relationship with God. If the Holy Spirit isn’t God and just a creature, He doesn’t know the mind of God. If the Holy Spirit isn’t God, He is no more use to us than an angel.

But the Father and the Son and the Holy Spirit is God. The Son has done for us and in our place what we could not do for God. Jesus has come and been perfectly obedient to all of God’s commands. Because He is God, Jesus can render that perfect obedience to God on our behalf. And the Holy Spirit works faith in that work to the Father and Son.

Dear saints, all of this is to say that because God is triune, He can perfectly love and save you by grace. Because God is Father, Son, and Holy Spirit, you are not simply His slaves or pets. You are the object of His love. God the Father has created you out of pure love. God the Son has redeemed you out of pure love. And God the Holy Spirit has sanctified you out of pure love. You are saved and redeemed to be God’s children.

Jesus, the eternal Son of God, has come into the world not to condemn you, but in order that you might be saved through Him. Blessed be the holy Trinity. Amen.

The peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus. Amen.
