This is the second time that John immediately recognizes Jesus upon meeting Him. The first was when they were both still in their mothers' wombs. There is a deep connection shown here.
We, too, are sought out by Jesus. We, too, can feel the connection with Him when He comes into our presence. There is something deep within our nature that allows us to recognize our savior, that longs to connect with Him in our lives.
Jesus did not go to the river to baptize John. Rather, He went to give John the opportunity for his actions to create a miracle. Jesus comes to us to help us fulfill our purpose as well.
