"There is hope in the Gospel for any man, so long as he lives. There is infinite willingness in Christ to pardon sin. There is infinite power in the Holy Spirit to change hearts. There are many diseases of the body which are incurable. The cleverest doctors cannot heal them. But, thank God! there are no incurable diseases of soul. All manner and quantity of sins can be washed away by Christ! The hardest and most wicked of hearts can be changed."
"Reader, I say again, while there is life—there is hope. The oldest, the vilest, the worst of sinners may be saved. Only let him come to Christ, confess his sin, and cry to Him for pardon—only let him cast his soul on Christ, and he shall be cured. The Holy Spirit shall be sent down on his heart, according to Christ’s promise, and he shall be changed by His Almighty power, into a new creature. "
