…know that nothing is easier for God than to give you victory over your enemies, whether they be few or many, whether they be old and strong or new and weak. Yet He has His own time and order for everything.
Therefore if a soul be overburdened with sins, if it be guilty of all the crimes in the world, if it be defiled beyond imagination; – if, at the same time, to the extent of its desire and strength, it uses every means and endeavor to become free of sin and turn to the path of good, but cannot get stable in anything right, however small, and, on the contrary, sinks ever deeper and deeper into evil; even if it is all that, it must not weaken in its trust of God or fall away from Him.
It must not abandon its spiritual weapons and strivings but must fight and fight, struggling with itself and with its enemies with all its courage and untiring efforts.
For know and understand, that in this unseen war all are losers except a man who never ceases to struggle and keep his trust in God; for God never abandons those who fight in His armies, although at times He lets them suffer wounds. So fight, everyone, and do not give ground; for the whole thing is in this unceasing struggle.
