This is the greatest definition in the Bible for sin. “Therefore to him that knoweth to do good, and doeth it not, to him it is sin.” (James 4:17, KJVS)These companion verses show what, "to him it is sin" means. John 16:7-9 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you. And when He is come, He will reprove the world of sin, and of righteousness, and of judgment: Of sin, because they believe not on Me;This is sin that leads to death, "Of sin, because they believe not on Me;" In Christ the Sin of the world has been overcome and we become like Him in this world. 1Jo 4:17 Herein is our love made perfect, that we may have boldness in the day of judgment: because as He is, so are we in this world. 1Jo 5:4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, [even] our faith. The sins of the Flesh are not the Sin of the World. Sins of the Flesh were taken care of at the Cross and repentance in our salvation and confession in our sins takes care of them. The Sin of the world is overcome by believing in Christ Jesus unto salvation, all else comes after new birth, because we then have the Faith of Jesus Christ in us that has overcome the world and we then can be forgiven of our sins, for, "God is Faithful and Just to forgive us our sins and cleanse us from all unrighteousness."Sin and sins, forgiveness of Sin unto salvation by believing In Christ Jesus. Sins overcome by the faith of the Son of God that is in us unto good works and fruit that overcomes the world. Jhn 16:33 These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world."In Me", this is our life, our overcoming, and our Glory. Colossians 1:27-28 To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory: Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:For it is no longer I who live but Christ who lives in me. Galatians 2:20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.In Christ: Phillip
