First Prayer of St. Macarius the Great
Orthodox Prayer Book

O God, cleanse me, a sinner, for I have never done anything good in I Thy sight;
deliver me from the evil I one, and may Thy will be in me, that I may open my
unworthy mouth without condemnation, and praise Thy holy Name of Father, Son
and Holy Spirit, now and ever, and to the ages of ages. Amen.
