The biblical definition of love goes far beyond romantic feelings or sentimental emotion. Love in the Bible is rooted in the character of God Himself—1 John 4:8 declares simply that God is love. The fullest expression of this agape love is found in 1 Corinthians 13, where Paul describes love as patient and kind, not envious or boastful, not self-seeking. This is unconditional love that bears all things, believes all things, hopes all things, endures all things—and love never fails. Jesus identified the greatest commandment as loving God with all your heart, soul, and mind, and the second as love your neighbor as yourself. The sacrificial love of God was ultimately demonstrated at the cross, where Christ laid down His life for sinners. Believers are called to love one another with this same self-giving devotion, making love the defining mark of those who follow Jesus.
