“And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment. Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.” 1 John 3:23-24.
“If I bear witness of Myself, My witness is not true. There is another who bears witness of Me, and I know that the witness which He witnesses of Me is true. You have sent to John, and he has borne witness to the truth. Yet I do not receive testimony from man, but I say these things that you may be saved. He was the burning and shining lamp, and you were willing for a time to rejoice in his light.” John 5:31-35.
