"For it is by grace you have been saved, through faith -- and this not from yourselves, it is the gift of God -- not by works, so that no one can boast."
Doesn't God know our human nature so well? (I know, duhhhh.) What I mean is He makes a way to salvation that takes no effort or display of our ability or discipline. Salvation is by faith alone -- this ethereal, unmeasurable belief that can only be seen in our hearts by God. Think about it. We each stand equals in faith -- it all will lead to salvation. If salvation was by how well we follow God's laws, we could scrutinize, compare, brag, and basically take credit for our own salvation. But God in His amazing wisdom designed a way where we must humble ourselves and simply believe and trust.
