So what is love? What does it mean to be loved by Jesus? Love means giving us what we need most. And what we need most is not healing, but a full and endless experience of the glory of God. Love means giving us what will bring us the fullest and longest joy. And what is that? What will give you full and eternal joy? The answer of this text (1 john 11:1-16) is clear: a revelation to your soul of the glory of God—seeing and admiring and marveling at and savoring the glory God in Jesus Christ. When someone is willing to die—or let your brother die—to give you (and your brother) that, he loves you.
Love is doing whatever you have to do to help people see and treasure the glory of God as their supreme joy—to help people see and be satisfied with the glory of God.
