And when ye stand praying, forgive, if ye have aught (anything) against any: that your Father also which is in heaven may forgive you your trespasses. But if ye do not forgive, neither will your Father which is in heaven forgive your trespasses (Mark 11:25-26). Forgiveness is easier said than done, but if we choose to submit ourselves to the Word of God, our Heavenly Father will give us a  heart to forgive.  You will know you have forgiven someone when you think about them or someone mentions their name  your emotions will not flare up. Forgiveness is more for the individual that has been hurt rather than the one that committed the hurt. Forgiveness release the individual that has been hurt; they will no  longer be tormented by hurt and anger. Unforgiveness is like carrying a ball and chain, it goes with you everywhere you go and no matter how you try to hide it; it will always be presence and it usually latches out towards someone  who has no idea what is going on with the individual.  Jesus instructed every disciples to forgive in order for their trespasses to be forgiven. When we forgive those that have hurt or wrong us, we will receive such a peace in our mind, heart and spirit. Unforgiveness is like cancer, it will destroy you, mentally and emotionally and it will also cause different sickness and diseases.  It  will also hinder answers to prayers as well as  your relationship with our Heavenly Father. Forgiveness is more powerful than any hurt or wrong someone may have done towards you. Confess forgiveness towards those who have hurt or wronged you; until you feel the manifestation in your emotions. God has promised, we have what we speak (And Jesus said unto them, because  of your unbelief: for verily I say unto you. If you have faith as grain of a mustard seed, ye shall say unto this mountain;  remove hence to yonder place; and it shall remove, and nothing shall be impossible for you. ( Matthew 17:20). Speak to the mountain of unforgiveness and tell it to be removed!
