How do we know that we love God?

According to 1 John 4:20, love for God is evidenced by love for our brothers. This passage emphasizes that if a person claims to love God but does not love their brother, they are deceiving themselves. The love of a believer is not just an emotional attachment; it is a commitment to seek the well-being of others, particularly fellow believers. True love for God compels us to love those who are in Christ, reflecting the transformative power of the Spirit within us that enables us to act in love and unity with God's people.
