Repentance is one of the most important words in the Christian vocabulary. The message of repentance is what Jesus focused on both at the beginning and at the end of His public ministry. And one cannot really follow Jesus if one does not understand repentance. So, what is repentance? What does it look like? How do we know if we have really repented? We see the negative demonstration of repentance from the story of Israel in Hosea 6 and 7. They may say the right words, bring along animal sacrifices, but ultimately, their hearts are far from God. God sees right through to their hearts and provides evidences of their hypocrisy. But this sermon also helps us see what real repentance is.
