Jesus said, Do it now because it is right for us to do everything the right way. So John dunked Jesus under the water because it was the sign that showed the start of new life in the Lord God of heaven. When Jesus came up out of the water, John saw the Holy Spirit come down out of heaven like a dove and land on Jesus.
Then the bad one took Jesus into the special city, Jerusalem, and set Him at the very top of the temple and said, If you are the Son of God, show me, throw yourself down because it is written in God’s book, He will give His angels to watch over you and they will catch you and keep you from falling even if you trip over a pebble in the road.
