To understand the imputation of sin, we must first recognize what is meant by “original sin,” the first sin of Adam, and the subsequent sinful nature inherited by every person because of his transgression. Our sinful nature is called depravity and consists of four things that are true of every man and woman ever born:

1. We are void of original righteousness.

2. We do not possess any holy affection toward God.

3. The depraved nature is within our hearts.

4. We have a continuous bias towards rebellion and evil.
