A quote from J.C. Ryle in his book "Repentance" :
“Sir,” said a young man to Philip Henry, “how long should a person go on repenting?” What did old Philip Henry reply? “Sir, I hope to carry my repentance to the very gates of heaven. Every day I find I am a sinner, and every day I need to repent. I intend to carry my repentance, by God’s help, up to the very gates of heaven.”
