Prayer for Spiritual Strength and Perseverance

I thank Thee, O holy Lord, almighty Father, eternal God, Who has deigned, not through any merits of mine, but out of Thy goodness, to satisfy me a sinner, Thy unworthy servant, with the precious body and blood of Thy Son, our Lord Jesus Christ.

I pray that this be not a condemnation to punishment for me, but a saving plea unto forgiveness.

May it be unto me the armor of faith and the shield of a good will.
May it be the emptying out of my vices and the extinction of all lustful desires;
An increase of charity and patience, of humility and obedience, and of all virtues;
A strong defense against the snares of all my enemies, visible and invisible;
The perfect quieting of all my evil impulses of flesh and spirit, and binding me to Thee, the one true God;
And a happy ending to my life.

I pray Thou would bring me, a sinner, to that ineffable banquet where Thou with Thy Son and the Holy Spirit, are to Thy saints true light, fulfillment of desires, eternal joy, unalloyed gladness, and perfect bliss.

Through the same Christ, our Lord.

Amen.
