From Unseen Warfare: You must never be afraid . . . that the enemy is too strong against you, that his attacks are never ending . . .

You must never be afraid, if you are troubled by a flood of thoughts, that the enemy is too strong against you, that his attacks are never ending, that the war will last for your lifetime, and that you cannot avoid incessant downfalls of all kinds. Know that our enemies, with all their wiles, are in the hands of our divine Commander, our Lord Jesus Christ, for Whose honour and glory you are waging war. Since He himself leads you into battle, He will certainly not suffer your enemies to use violence against you and overcome you, if you do not yourself cross over to their side with your will. He will Himself fight for you and will deliver your enemies into your hands, when He wills and as He wills, as it is written: ‘The Lord thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee’ (Deut. xxii, 14).

St. Peter of Damaskos: If we are not willing to sacrifice this temporal life, or perhaps even the life to come, for the sake of our neighbor . . .

“God says, ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your might’ (Deut. 6:5); yet how much have the fathers said and written – and still say and write – without equaling what is contained in that single phrase? For, as St Basil the Great has said, to love God with all your soul means to love nothing together with God; for if someone loves his own soul, he loves God, not with all his soul, but only partially; and if we love ourselves and innumerable other things as well, how can we love God or dare to claim that we love Him? It is the same with love of one’s neighbor. If we are not willing to sacrifice this temporal life, or perhaps even the life to come, for the sake of our neighbor, as were Moses and St. Paul, how can we say that we love him? For Moses said to God concerning his people, ‘If Thou wilt forgive their sins, forgive; but if not, blot me as well out of the book of life which Thou hast written’ (Ex. 32:32 LXX); while St. Paul said, ‘For I could wish that I myself were severed from Christ for the sake of my brethren’ (Rom. 9:3). He prayed, that is to say, that he should perish in order that others might be saved — and these others were the Israelites who were seeking to kill him.”
