The principle and source of the virtues is a good disposition of the will, that is to say, an aspiration for goodness and beauty. God is the source and ground of all supernal goodness. Thus the principle of goodness and beauty is faith or, rather, it is Christ, the rock of faith, who is principle and foundation of all virtues. On this rock we stand and on this foundation we build every good thing (cf. I Cor. 3:11).

Christ did not command the winds to cease at that time, but Himself stretched forth His hand and took hold of Peter, because here faith was required of him. When we do not do our part, divine (grace) slows and stands still.. . . it was not the wind that did Peter harm; his lack of faith sank him. Where faith is fruitfu, firm and strong, none of the evils that may befall us can do us any harm.
St. John Chrysostom
The Gospel Commentary edited by Hieromonk German Ciuba, 2002, 4th Century
And then we shall hear Him calling out and saying, Be of good cheer; it is I; be not afraid. This truth is supported by an understanding that the bad and terrible things of the present time are passing; they come and they go; therefore, fear not what is transient and evanescent. It is I, (He says,) meaning, I am ever-existent; as God I am He Who is. Do not betray your faith and your love for Me for the sake of the temporal things of the present.
St. John Chrysostom
The Gospel Commentary edited by Hieromonk German Ciuba, 2002, 4th Century
If, even after we have heard such words from Him, trials and temptations arise, and the tempests of evil spirits blow mightily, raging against us and afflicting us, and we are a little upset by the waves and their fury, the Lord will reproach our faint-heartedness, but will also stretch out His hand to us and grant us complete calm. If we desire with our bodies and souls to receive this, and not to be disturbed at all times by every wind of adversity, nor upset by the billows stirred up by men who gloat over other's misfortunes, we (must) know how very stormy the sea of life is, and what malice is aroused and seethes therein, and never let faith and hope in God be far from our minds.
St. John Chrysostom
The Gospel Commentary edited by Hieromonk German Ciuba, 2002, 4th Century
Let us, then, cry out loudly with Peter's words, "Lord, save us." And if we are willing to receive Christ into our ship; that is, to have Him dwell in our hearts; we shall immediately find ourselves at the land to which we are hastening. What land is that? Clearly, it is the promised land, heaven, the land of the meek, of them that refrain from evil. With them, then, may we also be vouchsafed to enter that land and be heirs of its good things; in Christ Jesus our Lord, to Whom be glory and dominion, with the Father and the Holy Spirit, unto the ages of ages. Amen.
St. John Chrysostom
The Gospel Commentary, edited by Hieromonk German Ciuba, 2002, 4th Century
So absolutely nothing does it avail to be near Christ, if not being near Him by faith .... Signifying therefore that not the assault of the wind, but his want of faith had wrought his overthrow, He said, "Wherefore did you doubt, O you of little faith?"
St. John Chrysostom
Homily 50 on Matthew 14, 4th Century
