Sin Nature and Committing a Sin?
Psalm 51:5 says “Behold I was brought forth in iniquity and in sin did my mother conceive me”; Romans 5:12 “Therefore just as sin came into the world through One man and death through sin and so death spread to all men”.
What propels motion and the motion itself is not the same. For instance, what propels a car to move is the workings of the engine (which is not seen) but the movement by tires rolling is obvious to all. The driving force of sin is in its nature we inherited; which man inherited at birth by the Original Sin at the Garden of Eden. This is what the Lord Jesus came to redeem us from (hence Paul referred to Him as the Last Adam in 1st Corinthians 15:45 “So it is written, “The first man Adam became a living being”; the last Adam, a life-giving Spirit”) and not the daily sins as listed in 1st Corinthians 6:9-10 “Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.” and Romans 1:29-31 “Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, Without understanding, covenant-breakers, without natural affection, implacable, unmerciful: Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same but have pleasure in them that do them.”
The daily sins are a reflection of a bigger problem (Sin Nature). It is like cutting a tree from the stem and leaving the roots. The tree will eventually grow back. That is why Matthew 3:10 says “The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire”. Even though this scripture is referring to hypocritical Christians(Pharisees and Sadducees), notice that the ax is at the root and not the stem or the branches because it is only at the root level can a tree be either utterly destroyed or properly nourished.
What makes a dog bark, a cat meow, a cow moo, or a lion roar is in their nature and that is what Jesus came to earth to save us from. We can not stop sinning by ourselves. Our righteousness is like a filthy rag before God(Isaiah 64:6) and even that cannot be sustained by our strength or intellect. We need Jesus.
