For word came to the king of Nineveh, and he arose from his throne, and he laid his robe from him, and covered him with sackcloth, and sat in ashes. Jonah 3:6
Bible verse,"And should not I spare Nineveh, that great city, wherein are more then six score thousand persons that cannot discern between their right hand and their left hand; and also much cattle?" (Jonah 4:11).
From God's words, we see that true repentance comes from deep within one’s heart.
Today's Bible verse is Acts 2:38. These words of Peter remind those who do not follow Jesus that: Repent, and be baptized in the name of Jesus Christ, their sins will be forgiven and they can gain God's guidance.
The Lord Jesus said, "Repent: for the kingdom of heaven is at hand" (Matthew 4:17). It can be seen that only those who truly repent can enter into the kingdom of heaven.
