When a person—crushed with grief—sins, then what benefit does he receive from this grief? The point is that the reason why we sin is because we are impatient and do not want to endure anything that goes against our will. However, God would never send us anything beyond our strength, just as the Apostle says: “God is faithful, Who will not allow you to be tempted beyond what you are able” (1 Cor. 10:13). But we do not have patience, do not want to endure even a little, do not attempt to accept everything with humility and therefore become overburdened. And the more we attempt to avoid these attacks, the more we suffer from them, get exhausted and are unable to rid ourselves of them. When a person endures temptation with patience and humility, it passes by without harming him. If he starts to be fainthearted, agitated and begins to blame others, then he will be burdened needlessly, inflicting upon himself even greater temptations without receiving any benefit.
