Do we forgive our neighbors their trespasses? God also forgives us in His mercy. Do we refuse to forgive? God, too, will refuse to forgive us. As we treat our neighbors, so also does God treat us. The forgiveness, then, of your sins or unforgiveness, and hence also your salvation or destruction, depend on you yourself, man. For without forgiveness of sins there is no salvation. You can see for yourself how terrible it is.
St. Tikhon of Zadonsk
Blessed is he who always has before his eyes that "the earth is the Lord's and the fulness thereof" (Ps. 23:1), and keeps in mind that God is powerful to arrange for His servants as is pleasing to Him.
