Master, which is the great commandment in the law?

John 1415 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.
