That is the truth in this material world in which we live. Jesus walked into the Jordan to be baptized that day. And by the way, most historical scholars do not deny this. He walked in and was baptized on that day in order to make the material world intersect with the spiritual world, with the Reign of God. Water is our reunion point.
Water is our intersection.
Where those two worlds collide, there it, water, takes on added meaning. You see, this story comes early in Mark and the other Gospels. And though it is told differently, it is in every Gospel. It is the beginning of Jesus public ministry. It is the point where he declares his allegiance and his plan.
