Here’s a prayer from Margery Kempe (1373–1432):

Lord, you say that no man may be drawn to you unless you draw him. Therefore, Lord, I pray that you will draw all people to you, regardless of how sinful they are. I never deserved to be drawn to you, Lord, and yet in your great mercy you drew me. If people around me knew my great wickedness as you do, they would marvel at the great goodness you have shown to me. If you can make such an unworthy creature as me worthy to be your servant, then you can turn the lowest sinner into the highest saint. I beg that you will turn all sinners into saints.
Amen.
