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.
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. John presents two tests distinguishing God's children from the devil's. "In this are manifest" (en toutō phanera estin)—what follows makes visible and identifiable the two spiritual families. The first test: "whosoever doeth not righteousness is not of God" (pas ho mē poiōn dikaiosunēn ouk estin ek tou theou). Habitual unrighteousness proves absence of genuine regeneration.
The second test adds a specific application: "neither he that loveth not his brother" (ho mē agapōn ton adelphon autou). Lack of love for fellow believers demonstrates one is not God's child. This introduces the major theme of verses 11-24—brotherly love as evidence of salvation. The present participles ("doeth," "loveth") indicate habitual character, not isolated failures. We all occasionally fail to love perfectly, but those who characteristically lack love for Christians reveal they're unregenerate.
These tests provide assurance and warning. Assurance: if you practice righteousness and love believers, you have evidence of genuine faith. Warning: if you live in unrighteousness and lovelessness, examine whether you truly know Christ (2 Corinthians 13:5). The children of God and children of the devil are distinguished not by claims or feelings but by observable patterns of righteousness and love.
Historical Context
The concept of two families—God's children and the devil's children—reflects Jesus's own teaching (Matthew 13:38, John 8:42-44). First-century Judaism distinguished between faithful Israelites and pagans, but Jesus and the apostles taught that ethnic descent didn't determine spiritual family; regeneration does. This challenged Jewish assumptions about automatic covenant membership through Abrahamic lineage.
The emphasis on loving "his brother" refers primarily to fellow believers, the Christian community. In the Johannine context, "brother" denoted spiritual siblings in God's family. This wasn't excluding love for outsiders (which Jesus commanded, Matthew 5:44) but highlighting that those who despise fellow believers demonstrate they're not truly born of God. The early church's radical love for one another attracted pagan notice ("see how they love one another").
