"The men of Nineveh will stand up with this generation at the judgment, and will condemn it because they repented at the preaching of Jonah; and behold, something greater than Jonah is here." (Matthew 12:41)
People who profess the name of Christ have no excuse for having their lives continually characterized by sin. A genuine faith in Christ will be evidenced by good works. It will be accompanied with a desire to serve God. These are the evidences of a changed heart. The lives of the apostles themselves are evidence of this truth. If we truly wish to inherit eternal life, then we must turn to God and seek the forgiveness that He provides. If we truly want a relationship with God, then we must follow Him on His terms. True repentance will inevitably result in a changed lifestyle. Repentance is the conviction that sin should no longer persist in our lives. We must recognize that we are spiritually bankrupt sinners who are in need of His redemption. A faith that saves is one that obeys. We need to be given a new heart. We need to be given a pure mind.
