Repentance is a soul-medicine that only Christ can mix and administer. If sorrow for sin be of our own or another's brewing, or if it is trusted in in place of His blood and merits, it is a toxic counterfeit, and not true repentance.
"Him God has exalted to His right hand to be Prince and Savior, to give repentance.." (Acts 5:13)
"And I will pour on the house of David and on the inhabitants of Jerusalem the Spirit of grace and supplication; then they will look on Me whom they pierced. Yes, they will mourn for Him as one mourns for his only son, and grieve for Him as one grieves for a firstborn." (Zech. 12:10)
