The Elohim of Genesis also speaks to the plurality of the Godhead. The Trinity is a mystery...taught, but not expressly so by name in Scripture. We see it clearly at Jesus' baptism. The wonderful thing is when Jesus ascended. He in a sense had to do this so as to have the Paracletos, our Helper come to us. Jesus was constrained by a physical body, though His Divine mind was always present in Heaven. What a great thing God has done for us in giving the Spirit, so that He could be with all of His children !
