5 And this is the message [the message of 1 promise] which we have heard from Him and now are reporting to you: God is Light, and there is no darkness in Him at all [ 2 no, not in any way]. 6 [So] if we say we are partakers together and enjoy fellowship with Him when we live and move and are walking about in darkness, we are [both] speaking falsely and do not live and practice the Truth [which the Gospel presents]. 7 But if we [really] are living and walking in the Light, as He [Himself] is in the Light, we have [true, unbroken] fellowship with one another, and the blood of Jesus Christ His Son cleanses (removes) us from all sin and guilt [keeps us cleansed from sin in all its forms and manifestations]. 8 If we say we have no sin [refusing to admit that we are sinners], we delude and lead ourselves astray, and the Truth [which the Gospel presents] is not in us [does not dwell in our hearts]. 9 If we [freely] admit that we have sinned and confess our sins, He is faithful and just (true to His own nature and promises) and will forgive our sins [dismiss our lawlessness] and [continuously] cleanse us from all unrighteousness [everything not in conformity to His will in purpose, thought, and action]. 10 If we say (claim) we have not sinned, we contradict His Word and make Him out to be false and a liar, and His Word is not in us [the divine message of the Gospel is not in our hearts].
