Love is indispensable to the body of Christ. This is the love that describes God.
The word for “love” is agape. This is God’s own description of Himself, 1 John 4:16, “God is love. This is a self-sacrificing love modeled by God Himself, John 3:16. This is primarily a love of volition rather than emotion.
The Corinthian Christians were not displaying this love. This love is a servant of our will not a victim of our emotions, Matthew 5:44, “love your enemies.” Jesus is not commanding emotion but action. Spiritual gifts were present in the Corinthian congregation, but true spiritual love was absent.
