God holds each of us by a string. When we sin, we cut the string. But God ties it up again, making a knot. Each time our wrongdoing cuts the string, God ties another knot drawing us up closer to Him.
Meister EckhartBehold how all those people are merchants who shun great sins and would like to be good and do good deeds in God's honour, such as fasts, vigils, prayers, and similar good deeds of all kinds. They do all these things so that our Lord may give them something, or so that God may do something dear to them. All these people are merchants.
Meister Eckhart
