Why does He need to be baptized or circumcised or born for that matter. He doesn’t need to do any of that. He’s God. He could have brought us salvation in any way he chose. But he chose to be born in a stable, be baptized, tempted by the devil, be tortured die and be buried. He also chose to give us His Precious Body and Blood and I choose to accept it all!
He did give us a way to have salvation.....believe in Him. It’s so simple most don’t understand.
