“Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned” – Romans 5:12
Inherent sin is provable, both in nature and from Scripture.
There was a video recently in which the speaker claimed that there is no inherent sin in man because the young are unaware of their sinful acts. I won’t link the video; we’ll stay attached closely to the truth lest we wander. But in this video, his children were acting up very near the beginning. He told the camera that his two-year-old is always doing bad things, but their behavior is not sin because the child does not know right and wrong.
Brothers and sisters, he disproved his point at the outset. One does not have to teach a child to strike another and take his toy. What made the child like this? To claim they are not sinners is to say that God made them rebellious, which, when you realize all men are sinners, is a claim that the source image of man is also a sinner; this is blasphemous! With no prompting or instruction whatsoever, children are sinners. Nobody had to teach them this. Even upon reprimand, children will continue to bear false witness, disobey a mother, steal, assault without good cause, and worse. They do this because they were born this way!
We are sinners, born of the seed of Adam, wholly wicked and depraved, even without remorse. It takes 12, 14, or 18 years to train a child in the way of Jesus Christ. Even then, much to his own dismay, though he would not, an adult born altogether anew by the Spirit of God sent from Heaven by Christ continues to flout the law of God in his heart, in his mind, and in his actions.
In fact, before salvation, the lost sinner may have some vague and darkened sense of right and wrong, but it’s almost always applied comparatively to other men. Man is born a sinner; unless and until the Lord opens their eyes, they are blinded by the devil to God and Christ; yet, created by God, they are His, without excuse before the throne on high. To acknowledge your sin, you must have knowledge of it, which is the miracle of salvation in Christ; that He is opening your eyes, showing your need for forgiveness and fear of hellfire. But Heaven help you, refusal to acknowledge your sin, even in ignorance feigned or actual, shall not save you at the final trumpet when Christ returns.
As to our verse at the top, the Scripture does not lie. Sin entered into the world through disobedience to God by the first man Adam, causing death. For this was the devil’s claim in the lie to the woman; “Ye shall not surely die.” But dead in sin, naked and afraid before Holy God, became the first man and his wife, and indeed his body expired, returning to the dust from whence he was taken, which was the very curse of God pronounced upon him for his rebelliousness. Disobedience to God is now in every man from his birth, so death passed upon all men, every single one, from Adam down each generation until today. There is no more clear evidence of sin than that every man’s life is but a vapor, appointed by God once to die; depravity of sin and the inevitability of death torments us all, for all that are in the world and the very earth itself are cursed by God for this sin.
But spoken in the word of God by the prophet Hosea, portending the day of Christ: “O grave, I will be thy destruction.” And later in the New Testament: “O death, where is thy sting? O grave, where is thy victory?” For what need a man of Christ if he is not a sinner bound to death unto the weight of the curse? Jesus himself said He came to save sinners. That you needn’t have to, Jesus tasted death for every man, for all have sinned and come short of the glory of God. That’s right; payment has already been made; accept it and call on Jesus.
Admit your depravity, abandon your pride, and seek forgiveness from God through faith in the atoning sacrifice of Jesus Christ. That’s why Jesus died on the cross, to pay your sin debt to Holy God. And now, Jesus having risen from the grave; by the very mercies of God Almighty, you need not die. Though your body will expire and be eaten by worms, those raised with Christ by the Spirit now will be raised again in the body, and with Job, we can proclaim to all the world: “For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth…yet in my flesh shall I see God.”
