The love of God is recognized because everyone who has God manifests the justice that comes from the Lord. Whoever commits injustice does not belong to God, but to the devil, since only the latter works in evil and uses those whom he deceives to perpetrate injustice.
This is why John refers to those who are from God and who demonstrate good works, those who practice justice and love their brother. If you are from God, you will show love towards your neighbor; Otherwise, you cannot consider yourself to be of God.
We must love our brothers and act justly, as the following verse from the first epistle of John urges us:
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
Those who are of the devil have no love for their neighbors; rather, they act unjustly toward their brothers. That is why the author claims that these are from the devil.
Looking at the title of chapter 3, it is clear: “Sons of God.” If we belong to the Lord and our Creator, who have placed eternal love in our hearts, we must manifest it, showing the mercy and divine justice of our Lord.
Let us love our brothers, as God has made us understand. Let us practice justice with others, demonstrating that good and faithful love towards them. God lives eternally in justice, love and truth; Let us not allow the evil one to bring bad influences into our lives.
