To love someone simply for the joy of loving them brings a love so much more complete and full in comparison to loving them in an effort to gain their approval or acceptance. We are free to love wholly, completely, and with abandon because Christ has qualified us as children of heaven. When our love is based on the finished work of Jesus, not the approval of man, it becomes a well that does not run dry because in Him we have all the approval we need, that being His death on account of His great love for us. It is this freedom, which comes through grace, that allows us to truly love unconditionally.
