JOHN 14 [15] If ye love me, KEEP MY COMMANDMENTS.[16] AND I WILL PRAY THE FATHER, AND HE SHALL GIVE YOU ANOTHER COMFORTER, that he may abide with you for ever;[17] Even THE SPIRIT OF TRUTH; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.[18] I will not leave you comfortless: I will come to you.[19] Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.[20] At that day ye shall know that I am in my Father, and ye in me, and I in you.[21] HE THAT HATH MY COMMANDMENTS, AND KEEPETH THEM, HE IT IS THAT LOVETH ME: and he that loveth me shall be loved of my Father, and I WILL LOVE HIM, AND WILL MANIFEST MYSELF TO HIM.
Believing JOHN 14 is not heresy
believing that God requires us to keep the 10 Commandments in order to be able to get the gift of the Spriit is heresy!
For its by faith alone one receives salvation and the Spirit from God!
