Sinners cannot understand the Bible!

[ecolox]

( there is only one God).

( God is three persons).

Well there ya go.

God is one - yet is described (or manifest) in these ways. ---This is similar to any immaterial idea being described/manifest in multiple ways. All these descriptions or manifestations indicate one idea. The fact that there are multiple descriptions or manifestations doesn't mean the idea is more than one idea in the end.

The Father is greater that I, and, I and the Father are one, are contradictory statements and you are failing to demonstrate otherwise.

Jesus was a human representation of God. God is greater in the sense that He is not human (or affected by physicality), yet Jesus and God are of the same essence, if you will.

Is this sufficient?
