Sure, I think that Baptism is performed in the same sense that infant circumcision was performed.
But, I think there’s more.
Why did Jesus tell John that He had to be baptized?
John was preaching a baptism of water and repentence. The water referred to the sign of God’s condemnation and punishment at the time of Noah. Jesus was, in my humble and respectful view, saying “I must have the sign of God’s condemnation and wrath put on me.” Water is the reminder for us that we deserve God’s condemnation and wrath for our sins.
John’s baptism was an alternate to the ritual baths that pilgrims took enroute to the Temple. And, John emphasized that the recipient should repent of his sins.
But, Jesus was sinless, and that’s why scripture says He got up immediately out of the water. Early Jewish Christians may well have understood Jesus’ action and we can very well understand it, too.
What did Jesus teach about baptism? He said that people would be baptized with the Holy Spirit.
So…the ‘repentence’ part makes us stumble about why infants can be baptized.
If baptism is delayed, then youngsters learn about their faith and learn about repentence and confession of sins. If baptism is administered early, youngsters still learn about their faith and learn about repentence and confession of sins, just as young Jewish boys learned about their faith after the circumcision.
But, not to disparage girls, Scripture talks about the circumcision of the heart, which is spiritual and refers to confession of sins and repentence for everyone.
Water is water, and immersion vividly recalls the flood of Noah’s time. But, water by pouring or sprinkling recalls the sign of God’s condemnation and His oath / covenant never to punish mankind for their sins that way again. Stay in your Bible.
Why did John say that he was unworthy to baptize Jesus?
Because he recognized that Jesus was sinless and he didn’t have the right to put God’s sign of condemnation on Jesus.
Why did Jesus say that John was the greatest prophet?
Because John prophesied that Jesus was the ‘Lamb’ that takes away the sins of the world. He connected everything in Jewish faith that preceded with Jesus’ ministry and death.
