I love these words from C. S. Lewis on how heartbreak can be something God uses to bring you nearer to Him. That sure was true for me.

“We shall draw nearer to God, not by trying to avoid the sufferings inherent in all loves, but by accepting them and offering them to Him; throwing away all defensive armour. If our hearts need to be broken, and if He chooses this as the way in which they should break, so be it.

As we look at the relationships in our own lives we might ask the following questions. Am I holding back my love toward God and others out of the fear of being wounded in the fray? If so, am I willing to begin to trust God with my life and open up the gateways to my heart so that I can both give and receive love as God intended me to do?” (from “The Risk of Love,” The Four Loves, C. S. Lewis)

There is no fear in love, but perfect love casts out fear.
For fear has to do with punishment, and whoever fears has not been perfected in love.
We love because he first loved us.
1 John 4:18-19 (ESV)
