The next in Paul’s list of attributes concerning the true love of God is that love is kind.
We look at the ways in which we can be kind to one another - spiritual kindness and physical kindness and consider examples in each case. Then we examine who should be the recipients of our kindness. We see that we are to do good to all but especially to the household of faith. We are to love our friends and our brothers and sisters in Christ but we are also to love our enemies and those who hate us. We must pay back good for the evil done to us and must lend without ever expecting to be repaid.
Finally, we realize that such love is beyond our own capacities and can only be within us through the Spirit of God. The demonstration of this kind of love serves as a source of assurance to us that we are believers. We see that the world and our own indwelling sin can quench the flame of this love. We need to return to Christ so that it may be fanned into flame once more. If we have never known this selfless love, then we are not Christians at all and must come in repentance and faith to the One who can cleanse us and ignite our hearts to burn with His love.
