Like Adam and Eve, we may try to do better. We may try to go do works of righteousness on our own. But we will fail as they failed. Our covering will be insufficient. Not because the world can see through it. Not because we can't fool our friends. Possibly the world won't see through it and our friends will be convinced. But we cannot trick God. He has already seen through our pitiful covering to the naked despair beneath it.
The Blood of Christ is the only sufficient covering for my sins, my mistakes, my faults, my lack, my weakness. Christ, according to his infinite mercies, has redeemed me. So when that conviction of the Spirit of God comes to me, and it awakens me from the spiritual daze that I've been living in, the thing I should do is run to grace. I should call out to God. I should trust in his righteouness that I can be made righteous (Romans 5), for that is the only way I can be.
Then, and only then, can I do right things for God. I can be what He calls me to be. I can fulfill His will in my life. You may not like that, but my Bible still says, "I can to all things through Christ which strengtheneth me." (Philippians 4:13).
