A Prayer From the Desert
Lord Jesus Christ, Whose will all things obey:
pardon what I have done and grant that I,
a sinner, may sin no more.
Lord,
I believe that though I do not deserve it,
You can cleanse me from all my sins.
Lord, I know that man looks upon the face,
but You see the heart.
Send Your spirit into my inmost being,
to take possession of my soul and body.
Without You I cannot be saved;
with You to protect me, I long for Your salvation.
And now I ask You for Your salvation.
And now I ask You for wisdom,
deign of
Your great goodness to help and defend me.
Guide my heart, almighty God,
that I may remember Your presence day and night.
Amen.
