Two great quotes that come via Wilbur Ellsworth (an Orthodox presbyter from the Chicago area) and his podcast called, “Let My Prayer Arise”:
The first comes from Eugene Peterson’s paraphrase of Psalm 51:10 (“Create in me a clean heart …”):
O God, make a fresh start in me. Shape a Genesis week from the chaos of my life.
The second comes from Ireneaus of Lyon (one of the Western Church Fathers who is very highly regarded by the Orthodox Church). It is an excerpt of a prayer to Jesus Christ:
For to not to be in you is not to be at all.
