No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us. Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit. ~ 1 John 4:12-13 KJV

No man has at any time [yet] seen God. But if we love one another, God abides (lives and remains) in us and His love (that love which is essentially His) is brought to completion (to its full maturity, runs its full course, is perfected) in us! By this we come to know (perceive, recognize, and understand) that we abide (live and remain) in Him and He in us: because He has given (imparted) to us of His [Holy] Spirit. ~ 1 John 4:12-13 AMP
