John 14:23-26 (King James Version)
23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him. 24 He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
25 These things have I spoken unto you, being yet present with you. 26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
