Romans 6:23If God bestows His gifts - especially salvation - in unmerited grace (pardon the redundancy), then my salvation and the blessing of God’s gifts have nothing to do with me. He doesn’t give them based on my actions or thoughts, how thankful I am or how much faith I have. He gives them based on His will, which is (very generally) to glorify Himself, and to make His children more like Christ.
I thank God grace is unmerited, because that is how He has set me free. Collect your own list of verses to substantiate that grace is unmerited. Choose one or two to memorize and meditate on. What are the effects of that truth?
