“I baptize you with water to show that you have changed your hearts and lives. But there is someone coming later who is able to do more than I can. I am not good enough to be the slave who takes off his sandals. He will baptize you with the Holy Spirit and with fire.
And that water is like baptism, which now saves you. Baptism is not the washing of dirt from the body. It is asking God for a clean conscience. It saves you because Jesus Christ was raised from death.
These things are copies of the real things that are in heaven. These copies had to be made clean by animal sacrifices. But the real things in heaven must have much better sacrifices.
These gifts and sacrifices are only about food and drink and special washings. They are only rules about the body. God gave them for his people to follow until the time of his new way.
