This sermon explores the biblical definition of Christian love as a self-giving commitment to act for the well-being of others, contrasting it with cultural views based on attraction or emotion. Drawing primarily from John 13 and 1 John 3, the message emphasizes that true love is active, non-discriminating, and affectionate, mirroring God's steadfast love for His people. The preacher challenges believers to demonstrate love through practical deeds rather than mere words or feelings, urging them to serve those in need without partiality. By grounding their conduct in Christ's example, Christians exhibit the greatest virtue that identifies them as disciples. Ultimately, the sermon calls for a life of obedient love that flows from receiving God's unconditional grace.
