Now then it is no more I that do it, but sin that dwelleth in me.Rom 7:17
The heart is deceitful above all things, and desperately wicked: who can know it? Jer 17:9
The reason why we are all prone to commit acts that are contrary to God and His laws is because we have a flawed, lawless and rebellious nature and this nature was inherited from our earliest Ancestors:Adam and Eve.
For as in Adam all die, even so in Christ shall all be made alive.1 Cor 15:22
If Adam and Eve had died before they had any offspring, we would never have existed. We would have died inside them. The Cursed and sinful nature that they inherited from the forbidden tree is the same nature that they passed to every Human being that came from them.
Our Focus must be on the Nature that Instigates Man to sin
Many times, we Christians tend to focus more on the lawless things that people do than on the thing that instigates them to do the lawless things that they do.
Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit.Matt 12:33
For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.Luke 6:44
If a man has a tree at the back of his house which produces fruit that is not edible and he wishes to have a tree that produces edible fruit on the same spot where the tree with the non edible fruit was planted, cutting the branches and leaves of the tree would not make the tree produce edible fruit. The only way he would be able to get edible fruit on the same spot would be to cut off the tree and plant a new tree that produces edible fruit.
He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.1 John 3:8
Jesus did not come to reform the works of the devil.He came to destroy them:He did not come to reform man on the outside i.e make them better sinners on the outside without any inner regeneration. He came to destroy the satanic nature that operates on the inside of humanity and regenerate and renew their hearts to become righteous.If Jesus mission on earth was simply to reform man,God wouldn't have bothered sending Him to die for our sins.He would have simply inspired prophets to tell mankind how to improve their morals and become better people.
I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.Gal 2:21
Jesus did not send His saints to reform the system of satan. He sent them to separate His Church from it and If we want to be part of the separated ones, we must be ready to die in order to partake of the glories of the new life that Jesus has on offer.
Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you.2 Cor 6:17
For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.Rom 6:6-5Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal.John 12:24-25
We must understand that the root cause of sin is the sinful nature that operates in the hearts of the children of men and not necessarily the things that the nature motivates them to do. Sin is not just about committing adultery,stealing and breaking the 10 commandments.There are millions of religious zealots who obey the 10 commandments but in the eyes of God they are the greatest sinners on earth because they have a heart that rejects God and resists His salvation plan for Humanity.
Woe unto you, scribes and Pharisees, hypocrites! for ye devour widows' houses, and for a pretence make long prayer: therefore ye shall receive the greater damnation.Matt 23:14
Stop trying to establish your own righteousness.Die to (destroy) yourself and submit to the righteousness of God.Any Righteousness that does not come from God is a 'fig leaf righteousness'.(Covering by self works) and it would be openly exposed as a superficial righteousness by the light of Christ .
And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.Gen 3:7
Woe to the rebellious children, saith the LORD, that take counsel, but not of me; and that cover with a covering, but not of my spirit, that they may add sin to sin:Isa 30:1
Stop trying to reform people on the outside. Always emphasize the need to die to the sinful nature that operates on the inside and the need for Christ's Spirit to work inside Man's heart. Any Righteousness that does not emanate from Christ is like filthy rags in the sight of God(Isa 64:6)
