One doubt arouse in my mind.If you see Gospel of John ch:10,v:29 My father is greater than all.......ch:14,v:28 says -My father is greater than I,On the other hand you gave a verse from ch:10,v:30- **I and My father are one, **Does this mean that the verses of bible are contradictory to each other??
Absolutely not. Jesus Christ came to earth as a servant. He submits Himself to the Father, even though He is all powerful, all knowing, and every bit as much God. The Holy Spirit submits to the Son and the Son submits to the Father. It's just the hiarchy that is set up within the Godhead. You can't have all three parts doing their own thing. He is still one God, yet resides in three persons. I can't totally explain it because I'm NOT God.
Here is another verse for you to ponder:
Jesus Christ admits that He is one and the same with the Father:
Joh 14:8 Philip said to Him, "Lord, show us the Father, and it is sufficient for us."Jesus said to him, "Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, 'Show us the Father'? "Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. "Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves.
