God Is Love

Verses 7-12 ground mutual love in divine origin: "love is from God," and those who love are described as born of God and knowing God. The statement "God is love" does not identify every human experience of love with God; the following verses define divine love through God's historical action in sending his unique Son. Verse 10 places initiative entirely with God: love consists not in humanity first loving God but in God loving and sending his Son as hilasmos, an atoning means concerning sins.

Verses 13-16 connect love with the Spirit and apostolic testimony. The gift of the Spirit provides assurance of mutual abiding, while "we have seen and testify" recalls the eyewitness language of 1:1-3. Confession that Jesus is the Son of God marks the believer's participation in this relationship. The repeated phrase "God is love" in verse 16 functions as a summary of the preceding argument: remaining in love corresponds to remaining in God because communal love derives from God's prior self-giving action.

Verses 17-21 relate perfected love to eschatological confidence. Love reaches its telos so that believers may have parrēsia, "confidence," in the day of judgment; fear associated with punishment is displaced by mature love. The statement "we love because he first loved us" summarizes the causal order. The final test is deliberately concrete: a person cannot credibly claim to love the unseen God while hating a visible brother or sister. Love of God and love of fellow believers are therefore presented as inseparable dimensions of the same command.

First John 4 continues the discussion of the Spirit from 3:24 by distinguishing trustworthy inspiration from deceptive claims to spiritual authority. Verses 1-6 command the community to test the spirits according to their confession of Jesus Christ and their relation to apostolic teaching. The immediate background is the schism described in 2:18-27: rival teachers claim spiritual insight but deny a christology the author considers essential. Their teaching is therefore interpreted within the wider opposition between the Spirit of truth and the spirit of error.

Verses 7-21 return to the theme of mutual love and ground it explicitly in God's own identity and saving action. The declaration that "God is love" is explained through the sending of the Son as the means of dealing with sin. Divine love becomes both the source and pattern of communal love, while the gift of the Spirit confirms mutual abiding between God and believers. The section culminates by linking perfected love with confidence at judgment and by declaring love for God inseparable from love for fellow believers.
