What Is Baptism? – Sermon for Midweek Lent 1

Listen here.

I. What is Baptism?

Baptism is not simply water, but it is the water used according to God’s command and connected with God’s Word.

What is this word of God?

It is the word of our Lord Jesus Christ, as recorded in the last chapter of Matthew: “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit.”

Martin Luther’s Small Catechism.

In the name of Jesus. Amen.

I’m no Julie Andrews, but I’ll attempt a little Maria von Trapp impersonation here, “Let’s start at the very beginning – a very good place to start. When you read, you begin with A-B-C. When you sing, you begin with Do-Re-Mi…” When you consider Baptism, you begin with Mt. 28:19.

Jesus says, “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” Our crucified and resurrected Savior, who has all authority in heaven and on earth, passes His authority to His disciples. But what exactly is Jesus telling His disciples to do here? What is the command? I can still hear and picture a particular missionary repeatedly telling a group I was in, “The command is to go!” Actually, it isn’t. And, in fact, the word ‘go’ is probably the least important word in this verse. That’s a horrible thing to say about anything Jesus tells us, but it’s true. In all honesty, you could remove the word ‘go’ and what Jesus says would have the same meaning. Just quickly, here’s why.

Before ascending into heaven, Jesus meets the disciples on a mountain in Galilee. Jesus wants His disciples to ‘make disciples’ of ‘all nations.’ Since ‘all nations’ are not there on that mountain, the disciples are going to have to leave the mountain in order to do what Jesus wants them to do. But because Jesus does say, “Go,” it is important. I don’t want to overly bore you here with grammar, so I’ll just get to the point. “Go,” is not a verb in Jesus’ sentence here. The idea is more along the lines of, “as you go,” in other words, wherever the disciples go, here is what they are to do. “Disciple all nations.” The command Jesus gives is ‘disciple,’ and ‘disciple’ is not a word that we are used to being an action. Normally, we hear the word ‘disciple’ and think it is a person – one of the twelve or a Christian today. But that’s the command, ‘disciple’ or ‘make disciples.’

And Jesus specifies whom the eleven disciples are to disciple – “all nations.” The word, there, for nations is ἔθνος – where we get our word ‘ethnicities’ or ‘all types of people.’ Jesus wants all ethnicities to be His disciples because – “red and yellow, black and white, they are precious in His sight.” And to fast-forward to when we will consider infant Baptism, that is one of the reasons we baptize infants. No matter their skin color, country, heritage, age, or ethnicity, Jesus wants all people to be saved and come to a knowledge of the truth (1 Tim. 2:4).

How are Jesus’ disciples to disciple all ethnicities? Two things are necessary: First, baptizing in the name of the Father, Son, and Holy Spirit, and second, teaching them all that Jesus has said.

Notice that, according to Jesus, the water of Baptism is tied to the divine, triune name of God – Father, Son, and Holy Spirit. God places His holy name on you in Baptism. But this is more than simply slapping a bumper sticker or luggage tag on you. When you were Baptized into the name of the Father, Son, and Holy Spirit, God brought you into fellowship with Himself. God gave you a new character, new identity, and even new birth.

When you put your name on a loan or marriage certificate, something changes. You are bound to an agreement or a person. When the eternal, unchangeable, holy God puts His name on you, that is significant.

That’s why teaching is also part of making disciples. It will take our entire lifetime to learn what it means to have God’s name placed upon us, the Baptized. That is why you come to church and listen to sermons, why you study and read your Bible. You have been made a disciple through water and the Word. Keep learning what that means, you children of God!

Now, some object to what the Bible says about God working spiritually through something physical like water. To that, we have to ask, “Has God ever used something physical to bring about salvation?” To that we have to say, without hesitation, “Yes!” Jesus became a literal, physical human to die on a cross, shed His blood, and rise again. In Christ, God used something physical to bring about something spiritual.

As humans, we are physical and spiritual – body and soul. So, it makes complete sense for God to save us through both physical and spiritual means – water and Word.

Now, it is vitally important that we recognize that Baptism isn’t simply water, but water used according to God’s command and connected to God’s Word. Without the Word and command of God, there is nothing special about the water used. That same water could be used to boil potatoes, wash your hands, or mop the floor. God’s Word and promise connected to that water is essential.

We might wonder, “Why would God chose to connect His promises to something as common as water?” God could have connected the same promises to honey, milk, or kiwi juice. But He didn’t. Asking why water is used in Baptism is like asking, “Why didn’t God create us with six arms? Why don’t birds say, ‘Moo’? Why doesn’t salt taste sweet?” The only answer is that God didn’t do it that way. Let’s let God be God, and let us be His creatures.

Again, God’s Word is essential to make a Baptism, but so is the water. Consider the importance of water through Scripture. It was over the water that the Holy Spirit hovered at the beginning of creation (Gen. 1:2). It was through water that God brought His people into the Promised Land (Jos. 3). It was through water that God led His people out of slavery (Ex. 14). It was with water that the priests were to wash their hands and feet before they went near the altar to minister to the Lord (Ex. 30:18-21).  And it was into the water that Jesus stepped to fulfill all righteousness (Mt. 3:15). 

Christian, as we will see in the coming weeks, in your Baptism God has done all of this for you. In your Baptism, the Holy Spirit has come to dwell in you. In your Baptism, you have been brought out of your slavery to sin. In your Baptism, you have been brought into the Promised Land of the kingdom of God. In your Baptism, you have been brought into God’s presence and before God’s altar. In your Baptism, God has fulfilled all righteousness and saved you. 

Finally, because Jesus commanded Baptism and as we see what it does in the coming weeks, we know that Baptism isn’t merely a human work. Baptism is God’s work. Just as God has redeemed you through the shedding of blood through Jesus’ hands, He has adopted you through the washing of water in Baptism done by human hands. In your Baptism, God gave you His grace, mercy, forgiveness, and adoption. It didn’t miss. Amen.

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