Since Jesus demonstrated abundant love for us on the cross, our relationships with each other are to develop that same abundant love.1. Love cooperates: lording it over others vs. cooperating with others for their joy. (1:23-24)2. Love is patient: the importance of the timing of Paul's next visit. (2:1-2)3. Love communicates: before Paul visited, his abundant love for them needed to be made known to them. (2:3-4)How can we know that God loves us?How are we to serve others? Mark 10:42-45, 1 Peter 5:3In what way are we free and slaves at the same time? Rom. 6:17-18Why is Christian love different from the world? Matt. 5:44-45
