I baptize you with water so that you will give up your sins. But someone more powerful is going to come, and I am not good enough even to carry his sandals. He will baptize you with the Holy Spirit and with fire.
At the feast there were six stone water jars that were used by the people for washing themselves in the way that their religion said they must. Each jar held about a hundred litres.
These rules are merely about such things as eating and drinking and ceremonies for washing ourselves. And rules about physical things will last only until the time comes to change them for something better.
These things are only copies of what is in heaven, and so they had to be made holy by these ceremonies. But the real things in heaven must be made holy by something better.
Those flood waters were like baptism that now saves you. But baptism is more than just washing your body. It means turning to God with a clear conscience, because Jesus Christ was raised from death.
