Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I.  And now I have told you before it come to pass, that, when it is come to pass, ye might believe. ~ John 14:28-29 KJV

You heard Me tell you, I am going away and I am coming [back] to you. If you [really] loved Me, you would have been glad, because I am going to the Father; for the Father is greater and mightier than I am. And now I have told you [this] before it occurs, so that when it does take place you may believe and have faith in and rely on Me. ~ John 14:28-29 AMP
