My soul, wait silently for God alone, For my expectation is from Him. 
He only is my rock and my salvation; He is my defense; I shall not be moved. 
In God is my salvation and my glory; The rock of my strength, And my refuge, is in God. 
Trust in Him at all times, you people; Pour out your heart before Him; God is a refuge for us. Selah

Spurgeon writes: The soul is apt to be dragged away from its anchorage, or is readily tempted to add a second confidence to the one sole and sure ground of reliance; we must, therefore, stir ourselves up to maintain the holy position which we were at first able to assume. Be still silent, O my soul! submit yourself completely, trust immovably, wait patiently. Let none of your enemies' imaginings, consultings, flatteries, or slander cause you to break the King's peace. ..

A living faith grows; experience develops the spiritual muscles of the saint, and gives a force which our religious childhood has not yet reached.

God who is our rock when we flee for shelter, is also our strong rock when we stand firm and defy the foe; he is to be praised under both characters.

Faith is an abiding duty, a perpetual privilege. We should trust when we can see, as well as when we are utterly in the dark.

His heart is set on you, lay bare your hearts to the Lord. Turn the vessel of your soul upside down in His secret presence, and let your inmost thoughts, desires, sorrows, and sins be poured out like water. Hide nothing from him, for you can hide nothing. To the Lord unburden your soul - let Him be your only father-confessor, for He only can absolve you when he has heard your confession. To keep our griefs to ourselves is to hoard up wretchedness.
