Some rabbis say that, at birth, we are each tied to God with a string, and that every time we sin, the string breaks. To those who repent of their sins, especially in the days of Rosh Hashanah, God sends the angel Gabriel to make knots in the string, so that the humble and contrite are once again tied to God. Because each one of us fails, because we all lose our way on the path to righteousness from time to time, our strings are full of knots. But, the rabbis like to say, a string with many knots is shorter than one without knots. So the person with many sins but a humble heart is closer to God.
