1) Where does it say that God created Adam and Eve without a sinful nature?
Romans 5:12~"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:"
Sin entered into the world by Adam's sin~he was
not created with sin in his members.
Jesus Christ was sent, not in the likeness of flesh, but in the flesh. He was sent, however, not
in sinful flesh, but in the
likeness of sinful flesh. Nothing can more clearly prove that the Lord Jesus Christ, though He assumed our nature, took it without taint of sin or corruption ~ that Adam received through being disobedience.
If the flesh of Jesus Christ was the likeness of sinful flesh, there must be a difference between the appearance of sinful flesh and our nature, or flesh in its original state when Adam was created. Christ, then, was not made in the likeness of the flesh of man before sin entered the world, but in the likeness of
his fallen flesh. Though He had no corruption in His nature, yet He had all the sinless infirmities of our flesh. The person of man, in his present state, may be greatly different from what it was when Adam came from the hand of his Creator. Our bodies, as they are at present, are called ‘the bodies of our humiliation,’ Philippians 3:21
(2) What is a sinful nature?
The lack of the original righteousness which God created Adam with. For our nature is not merely bereft of good, but is so productive of every kind of evil that it cannot be inactive but works in us. Those who have called it concupiscence (a strong, especially sexual desire, lust) have used a word by no means wide of the mark, if it were added (and this is what many do not concede) that whatever is in man from intellect to will, from the soul to the flesh, is all defiled and crammed with concupiscence; or, to sum it up briefly, that the whole man is in himself nothing but concupiscence. . . .every man, if honest would agree. to this.
(3) Where, in the Bible, do we read anything about a sinful nature?
Romans 5:12, Ephesians 2:1-3, and Psalm 51:5.
If by nature men are children of wrath, then their nature is sinful, or else God would be unrighteous saying they are children of his wrath by nature alone.
