This is from the book “Beginning Apologetics 2”
Those passages which describe Jesus as subordinate to God the Father ('the Father is greater than I am," Jn 14:28) refer to Him *as man. *They must be read in the light of other passages that refer to Him as God (“I and the Father are one,” Jn. 10:30; “He that has seen me has seen the Father,” Jn 14:9)
Jesus made statements about Himself that only God could make. For example, He said, “I am the way and the truth and the life”(Jn 14:6). No created being can say I am the life. Only God can say that about Himself because He is Life itself, and the source of life for all created beings. A creature can only say, “I have life.” The same applies to Jesus’ statement, “I AM the truth.” A creature can only say “I know the truth.” Only God can say I AM the truth because only God is Truth Itself.
Hope this helps
