Personally I don’t give a hoot about God’s mercy. If He wants to sit on His throne and dole out mercy to whomever He deems “worthy” so be it, but I really don’t care. It’s my life…and I get to decide how to live it. If that’s not good enough for God, then so be it. I’m willing to accept whatever judgment He chooses to dish out, but that’s His choice not mine.
I’m not averse to living my life in service to others, even God, in fact serving others is in my opinion one of the single most fulfilling things in life. But I do it because I want to, not because I’m under some obligation to, or because I need someone’s approval. I’m in no need of anyone’s mercy. I fully accept the consequences of my actions. If God wants to show me mercy, then show me mercy, but that’s His choice, not mine.
If God is truly merciful, then it’s not that there’s nothing that I can do to earn His mercy, it’s that there’s nothing that I need to do to gain His mercy.
