What does 1 John 3 say about the children of God?

In 1 John 3:10, we find a clear distinction made between the children of God and the children of the devil. This passage states that the children of God are manifested by their practice of righteousness and their love for their brethren. It emphasizes that true believers, as God’s children, will not only strive to live righteously but also display love, which is a fruit of the Holy Spirit at work in them. This union with Christ enables them to fulfill the command to love one another, reflecting the very nature of God as love.
