'Then
Jesus came from Galilee to the Jordan to be baptised by John. But
John tried to deter him, saying, "I need to be baptised by you, and
do you come to me?" Jesus replied, "let it be so now; it is
proper for us to do this to fulfil all righteouseness."'
St. Matthew 3:13,14
Jesus
lived the life God requires us to live. He lived a life which fulfilled
all the righteousness God requires of human beings. He lived it
perfectly for us and in our place.
