Repentance is turning away from your way of doing things. It is confessing that you need Jesus to make a change in your life. You can repent by asking God to change your heart. Tell Him about the areas in your life where you struggle. Talk to God about your desires and your story. He wants to hear from you.
Repentance is not a one-time act, but it is a lifelong process. Every time a harmful thought enters your mind, or you act outside of God’s principles, repent and turn it over to God. Each time you feel angry or distressed, you turn to God. He is our Father, and He wants to help.
