Almighty God, I believe that by worshipping and honouring You, I WILL overcome the attacks of the enemy. I tear down everything that the enemy has stripped from me and bind up every evil force that is attempting to penetrate my mind, heart, soul, because I know that whatever I bind on earth will be bound in heaven. If I have not yet forgiven, Lord, give me the grace and strength to forgive. Help me to trust again.
