I used to live near Amish communities and at a quilt show I heard that they will purposely leave one mistake in their project... to show that they are mortal and of course they make mistakes... that only God is perfect.
I don't know how to get through feelings of unworthiness though, in answer to the question posed.
I am sitting here this morning struggling with it as it relates to therapy. My weekly appointment is today and I don't feel like I deserve to be there, don't feel worthy of taking her time and energy. I love being there though and am committed to this so I'm going.
So I guess, worthy or not, here I come.
