Do you find yourself from time to time treating your sin as if it is no big deal, not as bad as some other people you know? If you do then you will fail to experience the full delight and freedom that comes from the forgiveness God offers. You will always carry around a hidden weight of pride mixed with some nagging guilt. The pride is your own flesh. The nagging guilt is the Holy Spirit trying to bring you to your knees so you can receive the full force of Gods love.
The only way to begin to love God with all your heart, mind, soul, and strength is to admit the depth of your sin. When you come to grips with that, and give up any hope of your own righteousness making the least bit of difference, then you are in position to receive Gods love. Only when you receive that love on that basis, the basis of your own complete and utter sinfulness, are you then in a position to live rightly, for the right reason.
Our reaction to God’s grace is a study in paradox. On the one hand we are extremely grateful for it and know that we need it. On the other hand we are often uncomfortable with it and seem to be concerned that a little too much grace might be a bad thing. We seem to be concerned that there will then be no motivation for living righteously. In some evangelistic presentations the question of what should motivate us to live rightly if we have all this forgiveness and grace is boiled down to a sense of gratitude for our forgiveness. With all due respect to those presentations, my gratitude runs out after a very short while. Certainly gratitude is a factor in obeying Jesus, but it is extremely limited in its effectiveness.
The Bible never speaks of gratitude as the reason for living righteously because gratitude is too weak a motivator. Jesus gives a rather different idea. He said very simply in John 14:15 that we will obey Him, keep is commandments, IF WE LOVE HIM! Love for God that comes as a response to His overwhelming forgiveness is what should motivate us to live differently. But in order to have that kind of love we must know and admit the depth of our sin. We do this not so we can wallow in some spiritual form of self-loathing but so we can understand the depth of God’s love for us. If you are not able to admit on a daily basis, the depth of your sin and the height of God’s mercy, you will not be able to love God with all you are.
