God's Love

There is no fear in love. But perfect love drives out fear, because fear has to do with punishent. The one who fears is not made perfect in love. - 1 John 4:18

I attended a Beth Moore Bible study class the other night and they were studying God's love.  Moore said that God's love is perfect and to be filled with God's love means that there isn't room in us for low self-esteem or fear.  Perfect love casts out fear.  But how do we fill up on God's love?  Is it a matter of will?  Or of sin? Or of letting go?  Perhaps it's simply a matter of knowing.  Knowing who we are in Christ and gleaning our security from that sacred place of grace.
