But whatever the origin, this saying clearly reflects the certainty that no man is perfect; he is born with the predisposition and capacity to commit transgressions, and do harm to himself, his fellowmen, and to God. He can never lay claim to a clear conscience. He has, at some point in his life, surely did something wrong, whether in word, in deed, or evern merely in his heart; he is guilty of wrongdoing, however trivial.
Not to demotivate, but just to remind myself — I am not perfect, I am not righteous.
If we claim to be without sin, we deceive ourselves and the truth is not in us — 1 John 1:8
for all have sinned and fall short of the glory of God — Romans 3:23
As it is written, “There is no one righteous, not even one” — Romans 3:10
