What does 1 John 4:8 means

1 John 4:8 states, "Whoever does not love does not know God, because God is love." This verse emphasizes the essence of God's character as love. It means that as believers, we are called to love others because love is a reflection of God's very nature. It also implies that if someone does not love, they do not truly know or understand God. Therefore, displaying love towards others is not only a commandment, but also an indication of one's relationship with God.
