There is a small but very important word found in (1Jn 1).
"IF"
It seems people have not notice this small but powerful word.
"IF" means "UPON THE CONDITION THAT."
That is a big "IF"
1Jo 1:6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
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.
Joh 15:6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.
Joh 15:7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
