Forgiveness is really for me

At cell group last Friday, we had a discussion on the Lord's Prayer (Matthew 6: 5-15). Our group focused on forgiveness.

v12 "Forgive us our debts,as we also have forgiven our debtors".
v14-15 "For if you forgive men when they sin against you, your heavenly Father will also forgive you. But if you do not forgive men their sins, your Father will not forgive your sins."

Wow...This is a stern warning. If we don't forgive others, God won't forgive us. We pondered. God is gracious and merciful. We reflected. God wants the best for us. Then, we concluded. Forgiveness is really for our benefit, and not so much for the person who have wronged us. Sometimes, the other person isn't even aware that he/she has offended us! Meanwhile, we allow bitterness, anger and hurt to eat us up causing us much emotional, spiritual and sometimes, physical damage. God wants us to release forgiveness so that we can be released. So you see, forgiveness is really for me.
