A primary goal of the spiritual life is to be more like Jesus. This is isn’t easy to accomplish on our own and we need all the help we can get.
Many saints offered prayers to Jesus, giving him their hearts so that God could mold their heart to be more like his.
Here is a traditional prayer that focuses on this “heart exchange.”
O most holy Heart of Jesus, fountain of every blessing,
I adore you, I love you and with a lively sorrow for my sins.
I offer you this poor heart of mine.
Make me humble, patient, pure, and wholly obedient to your will.
Grant, good Jesus, that I may live in you and for you.
Protect me in the midst of danger; comfort me in my afflictions;
give me health of body, assistance in my temporal needs,
your blessings on all that I do, and the grace of a holy death.
Within your heart I place my every care.
In every need let me come to you with humble trust saying,
Heart of Jesus, help me.
Amen.
