JMNT(i)
4 The person who keeps on saying, "I have come to know Him by experience, " and yet is not habitually keeping (observing) His implanted goals (impartations of the finished product within; inward directives), is a liar (exists being one who speaks falsehood) and God's Truth (the Reality of God; the Genuine Actuality which is God) is not (or: does not exist) within this one.
5 Yet whoever may be habitually keeping (attentively guarding to observe) His Word (Thought; Idea; message), truly (or: actually; in reality) within this person God's Love has been perfected and brought to its goal (or: the love which is God has been matured, finished and reached its purposed destiny). In this we constantly know experientially that we continuously exist within the midst of Him, and in union with Him.
6 The person habitually speaking [thus, as though] to be constantly abiding (remaining; dwelling) within Him, is continuously under obligation himself also to go on walking about (= behaving and conducting his life) just as That One (or: on the level and in the sphere as [He]) walked (or: walks; = lives His life).
