Your prayer for forgiveness is heard because you have called upon the name of the Lord Jesus Christ. Yet do not stop at a brief word, but learn from this very request how to draw near to God with a true and thorough repentance. The mercy of God is beyond measure, He has shown all longsuffering toward sinners, even making the foremost of sinners, Paul, a pattern of His patience so that no one might despair of pardon. But that same mercy calls you not to be careless about your sins, but to bring them into the light, specifically and honestly.
It is not enough to say, “Forgive me,” and remain ignorant of the wounds you carry. The best course is to avoid sin entirely, but when you have fallen, the next is to feel the sting of that fall and amend your life. The Evangelist tells us that Peter went out and wept bitterly after denying Christ, and so his sin was forgiven. That bitter weeping was the outward sign of a contrite heart. Esau, on the other hand, found no place of repentance because he did not seek it as he ought, he grieved over the loss of his birthright but not over the sin itself. Do not be like him. Examine your conscience, confess your specific offenses before God, and let your sorrow lead to a firm resolve to turn from them.
And if you fear that your sins are too great, or that you have sinned after receiving the knowledge of the truth, remember why Christ taught even the baptized to pray daily, “Forgive us our debts.” He did this to show that repentance remains a remedy after the laver of regeneration. The heavenly gift of forgiveness is not exhausted; you may yet taste its power. But take heed: while repentance is always available, do not presume upon it. A careless approach to sin can lead to a fall from which rising is made far more difficult, not because of any limit in God’s grace, but because the heart hardens and refuses true conversion.
Therefore, apply the remedies God has placed in your hands. Let your prayer be joined with fasting, almsgiving, and a humble spirit. Forgive others their trespasses against you, for in this you release your own soul from bitterness and open the door to mercy. Cultivate a contempt for worldly possessions and a hunger for the good word of God. In all things, give thanks to Him who desires not the death of a sinner but that he should turn and live.
So do not merely utter words; make your life a prayer of repentance. When you recall your sins, do not despair, look at Paul, the blasphemer, the persecutor, the chief of sinners, who obtained mercy precisely so that you might have courage. Let that mercy draw you to gratitude and a changed life. Keep the fear of judgment before your eyes to spur you on, but lean more heavily on the surpassing love of the One who calls you to Himself. Through sincere repentance, you will not only be forgiven but also restored and strengthened to walk in His ways.
