From his collected sermons, The Way Everlasting. The sermon concerns 1 Corinthians 13, on the call for Christians to love:
For what the theologian defines and the Apostle depicts is illustrated and embodied in our Lord Himself, and what we have to do is to look at Him. “Herein is love.” We do not know what love is till we see it in Jesus, and when we see it there we see Him identifying Himself with God’s interest in us. The revelation is not only made before our eyes, it is made with special reference to ourselves. In Christ’s presence we are not the spectators of love only, we are its objects. Christ exhibits towards men, He exhibits towards us, that wonderful goodness which Paul describes. When we think what our life has been, and what has been His attitude to us from first to last, do we not say, “Our Lord suffers long, and is kind; He is not easily provoked; He does not impute to us our evil. Where we are concerned, where God’s interest in us is concerned, He bears all things, He believes all things, He hopes all things, He endures all things.” These are the thoughts, or rather these are the experiences, out of which love is born in our hearts. We love, because He first loved us All the time it is His love which must inspire ours. “Beloved, let us love one another, for love is of God, and every one that loveth is born of God and knoweth God. He that loveth not knoweth not God, for God is love.”
