The Simplicity of Who Will Be "Saved"

"The Lord cannot justify and save any who cannot see their true condition.
 
The Savior came not to call righteous but sinners to repentance,
then none but sinners will be saved.

Now Romans 4:16, "therefore it is of faith."
Why?
That it might be by grace, "to the end that it may be sure."
