Have you ever wondered why Jesus was baptized?

The Lord was Baptized, not to be cleansed Himself, but to cleanse the waters, so that those waters, cleansed by the flesh of Christ which knew no sin, might have the power of Baptism.-St. Ambrose of Milan

(Is 42:1-4, 6-7)
Thus says the LORD:
Here is my servant whom I uphold,
my chosen one with whom I am pleased,
upon whom I have put my spirit;
he shall bring forth justice to the nations,
not crying out, not shouting,
not making his voice heard in the street.
a bruised reed he shall not break,
and a smoldering wick he shall not quench,
until he establishes justice on the earth;
the coastlands will wait for his teaching.

I, the LORD, have called you for the victory of justice,
I have grasped you by the hand;
I formed you, and set you
as a covenant of the people,
a light for the nations,
to open the eyes of the blind,
to bring out prisoners from confinement,
and from the dungeon, those who live in darkness
