And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment. John summarizes God's essential commands. "And this is his commandment" (kai autē estin hē entolē autou)—singular "commandment" with two inseparable components. First: "That we should believe on the name of his Son Jesus Christ" (hina pisteusōmen tō onomati tou huiou autou Iēsou Christou). Faith in Christ is commanded, not merely suggested. "The name" represents the full revelation of who Christ is—God's Son, Savior, Lord. Saving faith involves trusting in Christ's person and work.
Second: "and love one another" (kai agapōmen allēlous). Faith and love are joined—genuine faith produces love; genuine love stems from faith. These aren't sequential (first faith, later love) but simultaneous aspects of Christian life. "As he gave us commandment" (kathōs edōken entolēn hēmin) refers to Jesus's teaching (John 13:34, 15:12, 17). Christ commanded both faith in Him and love for one another.
This verse is remarkable—belief is commanded, not merely invited. This challenges the notion that faith is merely human decision; it's divinely commanded response to revelation. Yet God also enables the obedience He commands, granting faith (Ephesians 2:8) and love (Romans 5:5) to those He regenerates. The linking of faith and love shows Christianity's irreducible dimensions—vertical relationship with God through faith, horizontal relationship with others through love. Both are essential; neither alone suffices.
Historical Context
Judaism emphasized Shema (Deuteronomy 6:4-5): loving God with all one's being. Jesus added loving neighbor as second great commandment (Mark 12:28-31). John's formulation includes faith in Christ as the foundation for both loving God and loving others. This was Christianity's distinctive claim—faith in Jesus the Messiah was not optional extra but central command.
For first-century Jews considering Christianity, believing in Jesus as God's Son was the crucial hurdle. For Gentiles, monotheism and moral transformation were challenging. John presents both faith and love as divine commands, not human innovations. This grounds Christian ethics in divine authority—we love not merely because it's nice but because God commands it. We believe not merely because it seems right but because God commands it.
Questions for Reflection
How does understanding faith in Christ as a command (not merely an option) affect your evangelism and discipleship?
What's the relationship between believing on Christ's name and loving one another—can you truly do one without the other?
How do you obey the command to believe when faith itself is God's gift (Ephesians 2:8)?
