and water came out

Baptism is always going to be controversial -- not because He has planned it that way, but because there are vested interests that pull perspectives into various entrenched positions. I'm not going to argue about infant baptism, or sprinkling vs immersion, or whether baptism is necessary for salvation. The words used at the end of Matt3 caught my eye, but in the end, rather than argue about what they imply, I'm going to assert that He doesn't care about the mode or the meaning. He cares about the obedience.

Matt3 makes it clear to me that it is all about obedience. JtheB has a meaning behind the baptizing, and he is surprised that Jesus wants to be baptized. But the Lord cares not for John's meaning or mode or views on baptism. What the Lord cares about when He comes to the Jordan is that the Father commanded baptism, and He was going to obey.

A grand lesson for all.
