Repentance is turning from doing wrong to doing right. The Savior wants you to turn away from wrong and turn to Him. (See 3 Ne. 30:1 – 2.) He gave His life to pay for your sins so that if you repent, you can be forgiven and be clean again.
When you disobey the commandments or hurt others, the Holy Ghost cannot be with you and you may feel sad, guilty, lonely, or afraid. To change these feelings, you need to turn from doing wrong to doing right. Heavenly Father and Jesus Christ will help you change. This changing is called repentance.
Repentance begins inside of you — in your thoughts and in your heart. When you know you have done something wrong, think about it until a feeling of sorrow comes into your heart. Do not excuse yourself or blame someone else. Tell Heavenly Father what you have done and how you feel. Tell Him how much you love Him, and ask for His help. If you have hurt someone or something, try to make it better. Promise Heavenly Father that you will try, with all your heart, to do what is right from now on.
Repentance begins on the inside, but usually it shows on the outside as well. When you promise Heavenly Father that you will do what is right, you keep your promise by changing the way you act. You treat others with more love and kindness. You keep the commandments. These actions will help you feel good about yourself and others.
You will need to repent many times throughout your life. As you turn away from wrong and try to do what is right, you will grow closer and closer to Heavenly Father and Jesus Christ.
The Lord Jesus Christ has promised that if you repent, He will bless you and remember your wrongs no more. (See Hel. 13:11; D&C 58:42.)
