Everyone who calls upon the name of the Lord will be saved. (Acts 2:21)
In the Name + of Jesus. Amen. Jesus’ Name will save you. His Name delivers peace with God. His Name works peace with others through you. You trust Him; you have faith. That’s what “call upon His Name” means. You fear, love, and trust in Him above all things.
We killed Him, though. Our sins did. He was the long-promised, long-awaited Savior. When God shows up to save His people, to save sinners, they reject and kill Him for the trouble. Yes, He died for our sins; yes, we should have welcomed Him, but God used even our rejecting Him, killing Him, and turned it for good, eternal good. Now, there’s “no other Name under heaven by which we must be saved” (Acts 4:12).
The Spirit makes it all happen for you. He “cuts you to the heart” through the preaching of His Word. He brings you to Jesus, and Jesus to you, not only in the Word, but through Jesus’ gifts, too. Through Baptism the Spirit sanctifies us, cleanses our consciences, and makes us children of the Father, brothers with Christ. Through Jesus’ Supper, the Spirit unites us with Christ and His forgiveness in the eating and drinking of His Body and Blood. Through that same Supper, we have unity with each other in the bond of peace.
That’s how Pentecost ends. We always remember the tongues, but “those who received Peter’s Word were baptized, and 3,000 souls were added that day. And they were devoted to the Apostles’ teaching, to the communion that breaks bread, and to the prayers” (Acts 2:41-42). There the Spirit was “daily adding to their number those who were being saved” (Acts 2:47).
Actually, that’s how Pentecost continues for you. Yes, Pentecost continues for you. The work of the Spirit continues within you and on you. Through Jesus’ Word and Gifts, the Spirit grows, works, and creates His own gifts within you (Galatians 5:22-23). You call upon the Name of the Lord Jesus because of the Spirit. He’s working in the Word and the Body and Blood, just as He worked in the water and Word of your Baptism.
Now, you trust Jesus; you have faith. You call upon His Name. That’s what the Spirit continually does for you until He raises you from the dead on the Last Day. In the Name + of Jesus. Amen.
Spirit, water, blood entreating, Working faith and its completing In the One whose death-defeating Life has come with life for all. (Water, Blood, and Spirit Crying, LSB 597:5)
