Sin is the transgression of God's law, 1 John 3:4.
There cannot be a transgression if there is no law.
"For where there is no law, there is no transgression" Romans 4:15. There is no law because, "Christ is the end of the law for righteousness to everyone that believes" Romans 10:4. Jesus abolished the law by nailing it to his cross, Colossians 2:14. also Ephesians 2:15.
Sin is the transgression of Gods law, and that is why God gets rid of the transgressors..
Psalm 37:38 But the
transgressors shall be destroyed together: the end of the wicked shall be cut off.
Proverbs 2:22 But the wicked shall be cut off from the earth, and the
transgressors shall be rooted out of it.
Isaiah 1:28 And the destruction of the
transgressors and of the sinners shall be together, and they that forsake the Lord shall be consumed.
Hosea 14:9 Who is wise, and he shall understand these things? prudent, and he shall know them? for the ways of the Lord are right, and the just shall walk in them: but the
transgressors shall fall therein.
The law is to love our neighbour as ourselves, if you notice, Christ fulfilled that law of love.
If we believe in what Christ fulfilled, we shall keep His same ways, knowing that transgressors will b destroyed ( through lack of belief in the love of Christ, laying HIs life down for us to fulfil the righteousness of the law.)
We shall be judged by that same law of liberty, and if we believe in mercy, we will find mercy, if we don't do mercy, we show we do not believe in the mercy of Christ. ( we then deny that He died for us in Hs love and kindness.) We die without belief, as sin is the devils denial of the righteousness of God.
James 2:8 If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well:
9 But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.
10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
12 So speak ye, and so do, as they that shall be judged by the law of liberty.
13 For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment.
