We knew a man like that, DF, but his was a motorcycle wreck that uncovered cancer. He repented little, being a man of much foulness. And he died, leaving a widow and developmentally disabled adult son.
And I thought the Rest of the Story (thanks, Paul Harvey) was that the ambulance company was going to be sued for something. This is like the story about the guy who was hit by a car while out walking, taken by ambulance to the Emergency Room, where they did many tests and found he was suffering from another undetected problem. It saved his life because he was on the route to "Meet His Maker"
Do not presume on the riches of grace. Do you not know that Gods kindnesses are meant to lead to repentance? I hope this man knows the Lord, or that he is open to Truth. I pray God uses this for His Glory.
