There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love. We love because He first loved us.

Unless the Lord builds the house, those who build it labor in vain. Unless the Lord watches over the city, the watchman stays awake in vain. It is in vain that you rise up early and go late to rest, eating the bread of anxious toil; for he gives to his beloved sleep.
