"If you, LORD, kept a record of sins,
Lord, who could stand?
But with you there is forgiveness,
so that we can, with reverence, serve you."
We all have sin in our lives. It is the hereditary affliction of the spirit that we cannot cleanse by our own means, but daily make worse by our prolonged separation from God. You must acknowledge the universal reality of sin. Know that you will be held accountable for the sin in your life if you do not take up the mundificant that is Christ. He is the only means we have of spiritual redemption - something you may feel you do not need now but, I promise, you do and will even more when your time in this world is spent.
But grace is not offered to the dead. Only in life may you choose your side, choose if you will or will not be associated with Christ. Your death will be the seal upon your decision. Go to your grave knowing that this one thing will carry over, and not even mortality can annul your spiritual allegiance, which can either be a wonderful promise or a terrifying guarantee. Which will you make it?
