This story comes to mind.
Long story of which I’m paraphrasing, so bear with me.
In Daniel Defoe’s book, Robinson Crusoe, there is a part in the book which showed how powerful repentance and forgiveness is.
Robinson Crusoe was a staunch atheist, so much so, he and his father fought over it until he finally left. In his quest to seek religion free adventure, he set out to the Middle East to trade. Eventually, he was taken prisoner and made a slave in Algeria.
He finally was able to escape, but not without nearly starving to death and being killed in the process.
Anyway, he became a successful slave trader himself, when the slave ship he was on wrecked in a storm and washed against some rocks off the island he’d be stranded on for two decades.
Anyway, after scouting the island, he made it out to the shipwreck to see what he could salvage. He got some things and hoped to at least find some books to read. However, all were destroyed except the Holy Bible, which angered him. Of all the books to read, this is what he was left with.
Anyway, he took it ashore along with other things he might be able to use, but chose not to read the Bible. The problem was, in time he kept being drawn to read it and eventually to he did,
He began to see how wise and full of insight the Scriptures were. He then began to question his own atheistic beliefs and soon started to believe that God may truly exist. So he started to pray in his own way to God for help. However, as he received the gift of faith, he also saw his own true self and the state his soul was in the eyes of God. How could he such a wretched man turn to God, who is all holy and good ? He was struck with anguish over the realization of the sins he had and the inner torment caused him great grief. Throughout the night he tossed and turned until finally, he begged God to save him. Suddenly, his soul was filled with the Holy Spirit. Jesus came to him as his savior and gave him the intense feeling of love, compassion and most of all, forgiveness for all of his sins. Jesus became his Lord and Savior.
As he contemplated on what took place, he wrote in his journal that of all the suffering he had gone through in life, no relief compared to the forgiveness of his sins.
Again, I’m paraphrasing here, but Daniel Defoe was actually sharing his own religious experience in his book.
Repentance brings forgiveness, which is the most powerful thing we can experience from God.
