If you will not have death unto sin, you shall have sin unto death. There is no alternative. If you do not die to sin, you shall die for sin. If you do not slay sin, sin will slay you.
— Charles Spurgeon
Experience tells me that people's hearts are seldom changed if they are not changed when young. Seldom indeed are men converted when they are old. Habits have deep roots. Sin once allowed to nestle in your bosom will not be turned out at your bidding. Custom becomes second nature, and its chains are not easily broken.
— JC Ryle
For Death from Sin no power can separate
— John Milton
And when we love our sin then we are damned indeed.
