Baptism of Our Lord

Jesus is Revealed as Our Perfect Substitute

These are the Scripture readings for the Baptism of Our Lord.

God’s Word for This Week

“Why did Jesus need to be baptized? I thought baptism was for sinners?” That’s a common question among Christians. It doesn’t make sense that our perfectly sinless Savior would need to be baptized, yet he was. Why? Because Jesus had come to be our perfect substitute, and he is revealed as such in his baptism. God laid on him the sin of the world (John 1:29). Even from birth he endured the effects of our sin. Jesus wasn’t a sinner himself, but he was carrying our sin, pain, and sorrow (Is 53:4). He needed the assurance of God’s love and forgiveness, just as if he were a sinner himself. Jesus received those promises in baptism, just like we do.

First Lesson – Isaiah 49:1-6

Which person of the Trinity is speaking through the prophet Isaiah in these verses?


True or false: Jesus felt frustration in his job as Savior.

True. The Savior voices his frustration in verse 4. Sometimes he felt like he had “labored to no purpose” and that he had “spent (his) strength in vain and for nothing.” Yet Jesus persevered in his role as our perfect substitute.

What task has been given to Jesus?

Not only to “bring Jacob back to (God) and gather Israel” (i.e., Jewish Christians) but also to be “a light for the Gentiles” (non-Jews) that they might be brought to faith (John 10:16).

Second Lesson – Acts 16:25-34

How does the Holy Spirit work the faith that Paul encouraged the jailer to have in verse 31?

God works faith through the hearing of the gospel promises (Romans 10:17). In this particular instance, those promises were proclaimed in word and in the sacrament of Holy Baptism.

Who was baptized that evening?

The jailer’s whole household was baptized. We may assume that his household included both adults and children.

Gospel – Mark 1:4-11

What was the purpose of the baptism given by John?

The purpose was the same as the baptism we have today: it’s “a baptism of repentance for the forgiveness of sins” (Mark 1:4).

If Jesus was sinless, why was he baptized?

Though Jesus did not have any personal sin, in his role as Savior he was carrying the sins of the world. He had come to be our perfect substitute. He very much desired the promises of God that baptism gives sinners.

Which three special people were present at the baptism of Jesus?

The Holy Trinity (God the Father, the Son, and the Holy Spirit) were present at Jesus’ baptism. In the same way, the Holy Trinity was present at our baptisms, as we are baptized “in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19).
