The first lesson taught here is that of a forgiving disposition.

We pray, ‘ Forgive, even as we have forgiven.’

Scripture says, ‘ Forgive one another, even as God also in Christ forgave you.’
God’s full and free forgiveness is to be the rule of ours with men.Otherwise our reluctant, half-hearted forgiveness, which is not forgiveness at all, will be God’s rule with us. Every prayer rests upon our faith on God’s pardoning grace. If God dealt with us after our sins, not one prayer could be heard.

Pardon opens the door to all God’s love and blessing; because God has pardoned all our sin, our prayer can prevail to obtain all we need.
The deep sure ground of answer to prayer is God’s forgiving love. When it has taken possession of the heart, we pray in faith. But also, when it has taken possession of the heart, we live in love. God’s forgiving disposition, revealed in His love to us, becomes a disposition in us; as the power of His forgiving love shed abroad and dwelling within us, we forgive even
as He forgives.

If there be great and grievous injury or injustice done us, we seek first of all to possess a Godlike disposition; to be kept from a sense of wounded honour, from a desire to maintain our rights, or from rewarding the offender as he has deserved. In the little annoyances of daily life, we are watchful not to excuse the hasty temper, the sharp word, the quick judgement, with the thought that we mean no harm, that we do not keep the anger long, or that it would be too much to expect from feeble human nature, that we should really forgive the way that God and Christ do. No, we take the command literally, “Even as Christ forgave, so also do ye.”
