I will cry unto God Most High: unto God that performeth all things for me.
Yea, in the shadow of Thy wings will I make my refuge: until these calamities be overpast.
Be merciful unto me, O God, be merciful unto me: for my soul trusteth in Thee.
Almighty and everlasting God, who hatest nothing that Thou hast made and dost forgive the sins of all those who are penitent, create and make in us new and contrite hearts, that we, worthily lamenting our sins and acknowledging our wretchedness, may obtain of Thee, the God of all mercy, perfect remission and forgiveness; through Jesus Christ, Thy Son, our Lord, who liveth and reigneth with Thee and the Holy Ghost, one God, now and ever. Amen.
[I recommend WYDDQ‘s meditation on Lent, “Lent Extra Nos“, as well as the prayer posted by Pastor Weedon here from St. Andrew of Crete (don’t know who he is, but it’s a fitting prayer for this day).]
