Repent and Believe
So, the kind of change you need doesn’t come from out there; the kind of change you need comes only from God. And the Bible has a word for the kind of change that we need, and that word is “repent.” To repent means to change one’s minds, which leads to a change of heart and to a change of action.
Repentance is a genuine turning from sin toward God, in which you confess your need for God’s forgiveness through Christ. But repenting is only one side of the coin. The other side is faith. Coming into agreement that you are a sinner is a step away from sin, but you have to step toward something new. That’s where faith comes in. You have to step toward Jesus in faith to save you.
Faith is accepting the truth about Jesus Christ (namely His life, work, and promises), submitting to Him as Savior and Lord, and trusting Him alone for salvation and eternal life.
When you repent of your sins and place your faith in Jesus, the Bible says that Jesus comes into your life, God forgives your sin, and the Holy Spirit begins to heal the broken places in your life.
Another way of looking at it is to say that Jesus has restored your relationship with God.
