I recently stumbled into the following prayer from St. Ignatius Loyola, called the Dedication to Jesus. It think that it perfectly summarizes the ideal Christian attitude — the kind of submission and obedience that God looks for from each of us.

Lord Jesus Christ, take all my freedom,
my memory, my understanding, and my will.
All that I have and cherish You have given me.
I surrender it all to be guided by Your will.
Your grace and Your love are wealth enough for me.
Give me these, Lord Jesus, and I ask for nothing more.

Amen.
