AUV(i)
2 This is [one] way we know that we love God’s [spiritually reborn] children: [It is] when we love God and obey what He commands us to do.
3 For this is [real evidence of] our love for God: [It is] obeying what He commands us to do. And obeying His commands does not cause us any grief [or, unpleasantness].
4 For whoever [Note: The Greek says “whatever”] is [spiritually] conceived [and eventually born] by God will overcome [the evil influence of] the world. And this is [how] that victory can be gained over the world: [It is through] our faith [in God].
5 And who is the person who can overcome [the evil influence of] the world? [It is] the one who [truly] believes that Jesus is the Son of God.
