If we keep the path of virtue undefiled through devout and true knowledge, and do not deviate to either side, we will experience the advent of God revealed to us because of our dispassion. For 'I will sing a psalm and in a pure path I will understand when Thou wilt come to me' (cf. Ps. 101:1-2). The psalm stands for virtuous conduct; understanding indicates the spiritual knowledge, gained through virtue, by means of which we perceive God's advent, when we wait for the Lord vigilant in the virtues.

Do not say that faith in Christ alone can save you, for this is not possible if you do not attain love for Him, which is demonstrated by deeds. As for mere faith: "The demons also believe and tremble" (James, 2:19). The action of love consists in heartfelt good deeds toward one's neighbor, magnanimity, patience, and sober use of things.
Maximus the Confessor
If God suffers in the flesh when He is made man, should we not rejoice when we suffer, for we have God to share our sufferings? This shared suffering confers the kingdom on us. For he spoke truly who said, 'If we suffer with Him, then we shall also be glorified with Him' (Rom. 8:17).
Maximus the Confessor
But I say to you, the Lord says, love your enemies, do good to those who hate you, pray for those who persecute you. Why did he command these things? So that he might free you from hatred, sadness, anger and grudges, and might grant you the greatest possession of all, perfect love, which is impossible to possess except by the one who loves all equally in imitation of God.
