How do we know that every believer is totally depraved?
Answered in 1 source
Every believer recognizes their total depravity through the conviction of sin and the truth of Scripture that emphasizes mankind's fallen nature.
In 1 John 5:19, it is conveyed that believers know they are of God and that the whole world lies in wickedness. Every believer understands that the nature inherited from Adam is sinful. This recognition isn't subjective; rather, it draws from the consistent teaching of Scripture, notably in references like Romans 3:23 that all have sinned and fall short of the glory of God. It's this self-awareness, aligned with biblical truth, that highlights the depravity residing within them, as articulated in Romans 7:18, where Paul speaks about the inability of the flesh to do good.
