1 John 1:7-10 King James Version (KJV)
7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10 If we say that we have not sinned, we make him a liar, and his word is not in us.
1 John 1:7-10 Amplified Bible, Classic Edition (AMPC)
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].
1 John 1:7-10 Living Bible (TLB)
7 But if we are living in the light of God’s presence, just as Christ does, then we have wonderful fellowship and joy with each other, and the blood of Jesus his Son cleanses us from every sin.
8 If we say that we have no sin, we are only fooling ourselves and refusing to accept the truth. 9 But if we confess our sins to him,[a] he can be depended on to forgive us and to cleanse us from every wrong. And it is perfectly proper for God to do this for us because Christ died to wash away our sins.* 10 If we claim we have not sinned, we are lying and calling God a liar, for he says we have sinned.
