I think of Blessed Margaret Pole, one of my patrons I have adopted when thinking of confidence. She had to face the fact that she was being persecuted by her godson.
Such hard times.
While fulfilling our daily duties, then, we must abandon ourselves to almighty God in a spirit of deep faith, which must also be accompanied by an absolutely childlike confidence in His fatherly kindness. Confidence (fiducia or confidentia), says St. Thomas,  is a steadfast or intensified hope arising from a deep faith in the goodness of God, who, according to His promises, is ever at hand to help us—Deus auxilians. 
As the psalms declare: "Blessed are they that trust in the Lord" (2: 12) ; "They that trust in the Lord shall be as Mount Sion: he shall not be moved forever that dwelleth in Jerusalem" (124: 1) ; "Preserve me, O Lord, for I have put my trust in Thee" (15: 1) ; "In Thee, O Lord, have I hoped, let me not be confounded" (30: 1).
St. Paul (Rom. 4: 18) reminds us how Abraham, in spite of his advanced years, believed in the divine promise that he would be the father of many nations, and adds: "Against hope, he believed in hope.... In the promise also of God he staggered not by distrust: but was strengthened in faith,, giving glory to God: most fully knowing that whatsoever He has promised, He is able to perform."
Garrigou-Lagrange also writes about
providing us with “sustained moral energy”. This phrase deserves thought and
reflection. Sustained moral energy seems to me to be the ability to persevere
in times of trial and even harsh persecution. Providence
The great Dominican also notes that persistence in prayer is a sign of faith and the correspondence of prayer and believing in
If one is in sanctifying grace, one is moving towards and in the will of God.
Prayer, indeed, is a supernatural energy with an efficacy coming from God and the infinite merits of Christ, and from actual grace that leads us on to pray. It is a spiritual energy more potent than all the forces of nature together. It can obtain for us what God alone can bestow, the grace of contrition and of perfect charity, the grace also of eternal life, the very end and purpose of the divine governance, the final manifestation of its goodness.
He also states:
At a time when so many perils threaten the whole world, we need more to reflect on the necessity and sublimity of true prayer, especially when it is united with the prayer of our Lord and of our Lady. The present widespread disorder must by contrast stimulate us constantly to reflect that we are subject not only to the often unreasoning, imprudent government of men, but also to God's infinitely wise governance. God never permits evil except in view of some greater good. He wills that we co-operate in this good by a prayer that becomes daily more sincere, more humble, more profound, more confident, more persevering, by a prayer united with action, in order that each succeeding day shall see more perfectly realized in us and in those about us that petition of the Our Father: "Thy will be done on earth as it is in heaven." At a time when Bolshevism is putting forth every effort against God, it behooves us to repeat it again and again with ever deepening sincerity, in action as well as in word, so that as time goes on God's reign may supersede the reign of greed and pride. Thus in a concrete, practical way we shall at once see that God permits these present evils only because He has some higher purpose in view, which it will be granted us to see, if not in this world. at any rate after our death
