John 14:15, 21, 24

If ye love me, keep my commandments.

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.

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.
