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 cannot touch our hearts without creating love for our brethren. MB 113.2
After completing the Lord's Prayer, Jesus added: “If ye forgive men their trespasses, your heavenly Father will also forgive you: but if ye forgive not men their trespasses, neither will your Father forgive your trespasses.” 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. MB 113.3
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.” Isaiah 55:7-9. 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. David had the true conception of forgiveness when he prayed, “Create in me a clean heart, O God; and renew a right spirit within me.” Psalm 51:10. And again he says, “As far as the east is from the west, so far hath He removed our transgressions from us.” Psalm 103:12. MB 114.1
God in Christ gave Himself for our sins. He suffered the cruel death of the cross, bore for us the burden of guilt, “the just for the unjust,” that He might reveal to us His love and draw us to Himself. And He says, “Be ye kind one to another, tenderhearted, forgiving each other, even as God also in Christ forgave you.” Ephesians 4:32 , R.V. Let Christ, the divine Life, dwell in you and through you reveal the heaven-born love that will inspire hope in the hopeless and bring heaven's peace to the sin-stricken heart. As we come to God, this is the condition which meets us at the threshold, that, receiving mercy from Him, we yield ourselves to reveal His grace to others. MB 114.2
The one thing essential for us in order that we may receive and impart the forgiving love of God is to know and believe the love that He has to us. 1 John 4:16. Satan is working by every deception he can command, in order that we may not discern that love. He will lead us to think that our mistakes and transgressions have been so grievous that the Lord will not have respect unto our prayers and will not bless and save us. In ourselves we can see nothing but weakness, nothing to recommend us to God, and Satan tells us that it is of no use; we cannot remedy our defects of character. When we try to come to God, the enemy will whisper, It is of no use for you to pray; did not you do that evil thing? Have you not sinned against God and violated your own conscience? But we may tell the enemy that “the blood of Jesus Christ His Son cleanseth us from all sin.” 1 John 1:7. When we feel that we have sinned and cannot pray, it is then the time to pray. Ashamed we may be and deeply humbled, but we must pray and believe. “This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.” 1 Timothy 1:15. Forgiveness, reconciliation with God, comes to us, not as a reward for our works, it is not bestowed because of the merit of sinful men, but it is a gift unto us, having in the spotless righteousness of Christ its foundation for bestowal. MB 115.1
We should not try to lessen our guilt by excusing sin. We must accept God's estimate of sin, and that is heavy indeed. Calvary alone can reveal the terrible enormity of sin. If we had to bear our own guilt, it would crush us. But the sinless One has taken our place; though undeserving, He has borne our iniquity. “If we confess our sins,” God “is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” 1 John 1:9. Glorious truth!—just to His own law, and yet the Justifier of all that believe in Jesus. “Who is a God like unto Thee, that pardoneth iniquity, and passeth by the transgression of the remnant of His heritage? He retaineth not His anger forever, because He delighteth in mercy.” Micah 7:18. MB 116.1
