The Trinity (13)

Other implicit references to the Trinity in the Old Testament include Genesis 1:26, which reads, "Let us make man in our image, according to our likeness." Since God was alone at the time of creation (Isa. 44:24, Neh. 9:6) with no other gods, this expression of plurality must refer to God himself. At the Tower of Babel God says, "Let us go down," yet no one else comes down with him (Genesis 11:7).

Though Jesus does not water-down the strict monotheism—He directly quotes the Old Testament saying, “Hear, O Israel, the Lord thy God is one God.”  - however, he is far more explicit than these Old Testament references to God being a plurality.  

Matthew (11.27) and Luke (10.22) give us this statement: “No one knows the Son but the Father; and no one knows the Father but the Son . . .”: here are two persons put on one same level.  “I and the Father are one” (John 10.30): they are two persons, yet one. And when Philip the Apostle says (John 14.8), “Let us see the Father,” Our Lord answered: “Whoever has seen me has seen the Father.” Similarly, Our Lord says that He will answer our prayer (John 14.14) and that His Father will (John 16.23); that He will send the Holy Spirit (John 16.7) and that His Father will (John 14.16). Jesus is clearly conveying that God is at least two persons in one God: Father and Son.

In Christ, Ken.
