Jesus teaches that we can receive forgiveness from God only as we forgive others. It is the love of God that draws us unto Him, and that love can not touch our hearts without creating love for our brethren....
He who is unforgiving, cuts off the very channel through which alone he can receive mercy from God. We should not think that unless those who have injured us confess the wrong, we are justified in withholding from them our forgiveness. It is their part, no doubt, to humble their hearts by repentance and confession; but we are to have a spirit of compassion toward those who have trespassed against us, whether or not they confess their faults. However sorely they may have wounded us, we are not to cherish our grievances, and sympathize with ourselves over our injuries; but as we hope to be pardoned for our offenses against God, we are to pardon all who have done evil to us.
But forgiveness has a broader meaning than many suppose. When God gives the promise that He “will abundantly pardon,” He adds, as if the meaning of that promise exceeded all that we could comprehend: “My thoughts are not your thoughts, neither are your ways, My ways, saith the Lord. For as the heavens are higher than the earth, so are My ways higher than your ways, and My thoughts than your thoughts.”
God’s forgiveness is not merely a judicial act by which He sets us free from condemnation. It is not only forgiveness for sin, but reclaiming from sin. It is the outflow of redeeming love that transforms the heart.... God in Christ gave Himself for our sins.—Thoughts from the Mount of Blessing, 113, 114. WGD 233
“Heaven forming each on other to depend,
A master or a servant or a friend,
Bids each on other for assistance call,
Till one man's weakness grows the strength of all.” MH 496
Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven. Luke 6:37, KJV
