The horror you feel at your own sin is not a sign that you are cast out, but that the mercy of God is already stirring your heart. Do not imagine that the apostasy you read of closes every door. The words of Scripture that terrify you are a warning, not a sentence. When the Apostle says it is impossible to renew again to repentance those who have fallen away after tasting the heavenly gift, listen carefully: he does not say repentance is impossible, but that a second baptism is not given. He says “impossible” with regard to renewing again by the laver, that is, by the washing of regeneration. For repentance itself, far from being excluded, is commanded and given as a continual remedy for the faithful. Do you not pray each day, “Forgive us our debts as we forgive our debtors”? That prayer was not given to the uninitiated, but to believers. Christ Himself, knowing our weakness after the font, made this rule of supplication precisely so that we might daily wash away our offenses. If forgiveness were not available to those who fall after baptism, He would never have taught us to ask for it.
Your tears, your cry for mercy, your confession that you have been foolish, these are the birth pangs of repentance. But see that your repentance is genuine, not mere fear of punishment. Esau also wept and sought the blessing with tears, yet found no place of repentance. Why? Because his grief was not of repentance but of worldly sorrow; his intention was still to kill his brother. True repentance is not just weeping over consequences, but a firm turning of the will away from sin, a hatred of the evil itself, and a resolution to pursue what is good. Do not merely look backward with dread; press forward in mercy and contrition. Let your tears be joined to almsgiving, for alms deliver from death and grant us a great light before God. Show mercy to others, and mercy will be shown to you. Forgive every debt and every wrong, and your own debts will be forgiven. Nothing so provokes the tender heart of God as to see a sinner make himself a vessel of mercy by showing mercy.
The long-suffering of God has endured your wandering precisely to lead you to this moment. Pharaoh was a vessel of wrath fitted by his own hard-heartedness, yet God endured him with much long-suffering, willing him to repent. If God bears with the stubborn, how much more has He been patient with you, not wishing you to perish but to come to repentance? What you now feel is that long-suffering having its fruit. Do not let the enemy persuade you that you have sinned too greatly. There are innumerable remedies: prayers, fasting, a contrite heart, contempt of worldly things, and above all, mercy. Pour these ointments on your wounds. The physician is ready; the medicine is prepared. Only do not delay, and do not merely grieve, change your life. Prove your repentance by deeds, and you will find the Savior’s mercy far surpassing your sin.
