And forgive us our debts, as we forgive our debtors. For thine is the kingdom, and the power, and the glory, for ever. The Lord's Prayer says it all. It has all we need to pray for. But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Forgiveness is a key part of answered prayer.
We are to forgive others, accept our own forgiveness, and then forget as our Father does on our behalf. A key to forgiveness is forgetting. When it is forgotten, that is true forgiveness. Even pray for those who persecute you or want to harm you. Pray as Jesus did early and late, seeking guidance.
