1 John 3:10
In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
1 John 3:10
This verse draws a clear line between the children of God and the devil, visible in conduct and love for others. The criteria: righteousness and love for brothers. The language sets a societal standard within the community: who you are is evident in how you live and treat others, particularly siblings in faith. John’s claim is not purely individualistic but communal, emphasizing social ethics as proof of allegiance to God or the devil. The reference to “not of God” because of the absence of righteousness and brotherly love serves as a sober reminder to examine one’s habits and affections.
Key themes: ethical identity, communal faith, and the evidencing of new life. The verse anchors salvation in both personal belief and relational behavior; true Sonship yields fruit that includes care for others.
Apply by evaluating how you treat others, especially those within your faith community. Do you seek justice, reconciliation, and tenderness toward a brother or sister in need? If you claim God’s family membership, let love and righteousness be the unmistakable marks. If you see unloving patterns, invite accountability, address conflicts, and adjust priorities to reflect God’s love.
