Prison

He who is often rebuked, and
hardens his neck, will suddenly be
destroyed, and that without remedy. 
Proverbs 29:1

Prison is a place where a man either comes to an end of himself... 

...and his own devices, and admits his wrongs and calls out to Christ, or he allows his heart to harden further as he delves deeper into the darkness of his sin.

As the Bible states, after receiving many "rebukes" and wake-up calls from the Lord in His efforts to reach that wayward man (usually over a period of many years) God may eventually choose to end His efforts to save that soul.

I know from my own experience that the Lord is very patient. He is merciful and eager to forgive. But if a man wishes to turn his back on God's mercy, then he will only continue his downward spiral into Hell.

Prison, therefore, is a place where a man will either make his peace with God through faith in Jesus Christ and thus receive God's forgiveness, or he will continue on the path to self-destruction where eternal damnation awaits him in the fires of Hell.

Every man has his own choice to make. But the Lord will not wait for him forever.

D.B.
