When speaking about spiritual issues, one word that tends to get a reaction is the word "repent." I don't have any hard evidence to back this up, but my gut feeling is that when most people hear that word, they tend to feel somewhat negative toward it. It's a word that demands that a change be made. To repent may involve regret and remorse, and if it's genuine, will also involve a change of direction.
The Lord invites us to be people who repent. We're encouraged to be people who practice repentance as a regular feature of our growing faith in Jesus Christ. When we first became aware of our need for His gift of salvation, we repented of our unbelief, stopped embracing the sin we once idolized, and began trusting in Him. As our relationship with Him continues, we're invited to continue to practice repentance every time we become conscious of sin or unbelief in our lives. It isn't dreadful to repent, it's joyful because we know our Lord loves us and is eager to welcome us into His presence. He doesn't hate us when we make mistakes. He loves us and invites us to return to Him so we can experience His cleansing.
Luke 16:19-31 illustrates our need to repent of our unbelief, and I'd like to point out four specific reasons why we should do so.
