Is God greater than Himself?:

Okay, If Jesus and God are two distinct gods and one is greater than the other ("my Father is greater than I" John 14:28) then this contradicts such verses as Isaiah 43:10-11 and the very definition of the "Trinity" (see section 2.2.5) which includes the words: "..Co-equality.." in its definition (see section 2.2.8).

However, if they are not two separate gods, but ONE god, as claimed by all Trinitarians (like Mr. J), then is Jesus (pbuh) praying to himself? Is, for instance, his mind praying to his soul? Why?
