(Mat 19:17 KJV) And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
What of this. Jesus was speaking of His flesh nature.. unless you believe he is not God.
(John 14:10 KJV) Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
Again, unless you place a difference between the two natures of flesh and spirit, and recognize that Jesus was limited in His humanity by design, you will run into problems here. Jesus "dices up" the aspects of his person here, not me.
