1 John 4:20-1 John 5:5 - Keeping God's Commands
20 If a person says, "I love God," yet [in reality] hates his brother, he is a liar. For the person who does not love his brother, whom he has seen, cannot [possibly] love God, whom he has never seen. 21 And this is the [greatest] commandment [See Matt. 2:37-38] we have received from Him: [It requires] that the person who [claims to] love God should also love his brother.
1 Every person who believes that Jesus is the Christ [i.e., God's specially chosen one] has been [spiritually] conceived [and eventually born] by God. And everyone who [continually] loves God, who did the conceiving, also [must continually] love the person whom God has [spiritually] conceived. 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.
