21. Did mankind need a Saviour?
Yes . The fall of Adam and Eve resulted in the human race falling into the bondage of sin from which we could not save ourselves.
23. For all have sinned, and come short of the glory of God;
6. But we are all as an unclean thing, and all our righteousness are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.
