It is not a movement of a special section or a special function of man's total being. They all are united in the act of faith.
Do you purchase the first tree you see? Of course not. You search for the right one. You walk the rows. You lift several up and set them down. You examine them from all angles until you decide, This one is perfect. You have a place in mind where the tree will sit. Not just any tree will do. God does the same.
