I found this prayer in an Ash Wednesday post at the Perigrinatio blog.
I beseech You, Jesus, Loving Saviour to show Yourself to all who seek You, so that we may know You and love You.
May we love You alone
and desire You alone
and keep You always in our thoughts.
May love for You possess our hearts.
May affection for You fill our senses
so that we may love all else in You.
Jesus, King of Glory
You know how to give greatly
and You have promised great things.
Nothing is greater than Yourself we ask nothing of You but Yourself.
You are our life
and our drink
and our All.
In the name of the Father, and of the Son and of the Holy Spirit our All in All, Amen. (From A Celtic Primer compiled by Brendan O’Malley)
