Here is a short prayer from Fr. Francis Xavier Lasance’s book ‘With God’ that begs God for a more loving heart.
Rekindle your Love for God to grow with this Short Prayer
My Jesus, you well know that I love you, but I do not love you enough. Oh, help me to love you more. O Love which burns always and is never extinguished, my God, you who are charity itself, kindle in my heart that divine fire which consumes the saints and transforms them into you. Amen.
