For it is by grace you have been saved,
and this is not from yourselves,
it is the gift of God—
not by works,
so that no one can boast.
God offered me the chance to have Him as my master. That's a gift from Him that I decided to open. I did have a choice to either accept His offering or not. I stepped out in faith.
I had done nothing to deserve His favor but He offered me His life anyway. I have done nothing about which I can boast except how Christ has worked in me. I'm a pretty pitiful participant in His eternal offering but somehow he delighted in me enough to offer me eternity. I'm thankful.
