Sermon for the Festival of the Holy Trinity based on John 3:1-15
Dear people born again by water and the Spirit: grace, mercy, and peace to you from God the Father and our Lord and Saviour Jesus Christ. Amen.
Nicodemus went to Jesus at night and they had a conversation about how one gets into heaven. Jesus’ answer to Nicodemus is so simple and easy that he struggled to grasp it or understand it. Jesus said, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.” Yes, the water of Baptism which gives you the Holy Spirit brings you into the kingdom of God. That’s it. That’s how you get into heaven – through Baptism.
“How can these things be?” Nicodemus asks. Surely it must be more difficult than that. Surely I must do something. There must be rules for me to follow to distinguish myself from others. Surely I must make some grand confession before witnesses, study the Scriptures, and go to church. Jesus says, no. The way to heaven is by being reborn of water and the Spirit.
How can these things be? Because Jesus says so. Because Jesus gives you the forgiveness of sins through Baptism. He puts His name on you and claims you for Himself in Baptism.
Heretical spirits will say that Baptism is not important; that it is a useless ceremony. We are saved by faith alone, they say, so we don’t need Baptism.
We have God’s Word and command that have instituted, established, and confirmed Baptism. What God institutes and commands cannot be useless (LC IV.8). Thus, God promises, “Whoever believes and is baptized will be saved.” (Mark 16:16)
What is faith without Baptism? Faith in what? Faith must have an object – faith must have something to believe – something to which it can cling and upon which it may stand (LC IV.29). Faith clings to God’s promises. God promises, “Whoever believes and is baptized will be saved.” Faith clings to God’s promise that we are baptized into the death of Christ, and we therefore get all the benefits of Jesus’ death through our Baptism into Him (Rom. 6).
Of what use is Jesus’ death on the cross if you do not receive the benefits of His death? If you do not personally receive the forgiveness of sins Jesus earned by His suffering and death, His death is of no advantage to you.
How important is Baptism? Jesus says, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.” If you’re not baptized, you’re not getting into heaven. That’s how important Baptism is.
If Baptism is so powerful and gives the forgiveness of sins and saves from sin, death, and the devil, and brings us into Christ’s kingdom to live with Him forever, why do we need anything else? Why do we seek to follow God’s commandments? Why do we need God’s Word, Absolution, the Lord’s Supper? Why do we go to church?
We seek to follow God’s commandments because they are for our good. They are God’s good and perfect will for our lives. There is no better way to love God and your neighbour than following the commandments of God. There is no better way to live than the way God created you to live.
We need to hear God’s Word so that we can hear His commandments and how He wants us to live. In His Word we also hear His promises, including the promises He connects to Baptism. God has given us Absolution and the Lord’s Supper to continually give us forgiveness because we fail to follow His commandments perfectly. He uses them to continually strengthen our faith to life everlasting. These things God gives to you in His Church on earth, and that’s why we go to church.
This is why parents and baptismal sponsors make promises to bring the child to church and eventually to the Lord’s Supper. The faith given in Baptism will die if it is never nurtured by God’s Word. Jesus didn’t give us His Word and institute the Sacrament of the Altar because we don’t need them and don’t benefit from them. He gave them to us because He knows we need them to bring us to everlasting life.
Do not neglect the means of grace that give you life. They are for your benefit. Baptism is what has brought you into the kingdom of God. God’s Word and the Lord’s Supper keep you in the kingdom of God. That’s why your salvation is sure. It is not up to you. It is up to God.
God has brought you into His kingdom here on earth and keeps you in His kingdom so that He will also bring you into His kingdom of heaven. His kingdom here on earth is His Church. Through His Church on earth, He brings you into His kingdom of heaven, because through His Church on earth He baptizes, feeds, and nourishes you with His Word and the body and blood of Jesus.
Jesus’ suffering and death for the sins of the whole world doesn’t benefit you if you are not actually receiving forgiveness. That is why Jesus instituted the church and the means of grace – the ways that He gives you forgiveness, which are His Word and sacraments. They are not useless ceremonies, but they are the miraculous way that Jesus gives you forgiveness and brings you to eternal life. Amen.
The peace of God which surpasses all understanding, will keep your hearts and minds in Christ Jesus our Lord. Amen.
