“He restores my soul.” Psalm 23:3
“When we take the history of a child of God, compressed within the short period of a single day — mark what flaws, what imperfections, what fickleness, what dereliction in principle, what flaws in practice, what errors in judgment and what wanderings of heart make up that brief history — how we are led to thank God for the stability of the covenant, that covenant which provides for the full redemption of all believers, which from eternity secures the effectual calling, the perfect keeping and certain salvation of every chosen vessel of mercy!”
Octavius Winslow, Personal Declension and Revival of Religion in the Soul (London, 1962), page 169.

Already Not Yet 
The “stability of the covenant” empowers us to press on when “What’s the use?” and “I give up!” keeps screaming in our lives.
I believe you have a flaw in the date. 😉 It probably should be 1862, not 1962.
