And we have known [with certainty] and have believed [with assurance] that God has truly loved us. God's [very nature] is love and the person who [continually] loves [Him and others] lives in [fellowship with] God [continually], and God [continually] lives in that person's heart.

The person who [sincerely] believes in God's Son has the evidence [of it] within his heart, [confirming God's testimony]. The person who does not believe God [i.e., what He says about Jesus], accuses Him of lying, because he has not accepted the [irrefutable] testimony of God concerning [the identity and mission of] His Son.

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.

No one who has been [spiritually] conceived [and eventually born] by God continues to live a sinful life, because God's seed [i.e., His word, See Luke 8:11] continues to live in his heart, so he cannot [continue a life of] sin, because he has been conceived by God.

And this is how we will know that we are following [God's] truth, and will have assurance [of it] in our hearts and before God [as well].

But, if our hearts condemn us [for not demonstrating God's love for others], surely God, who is greater than our hearts [will also condemn us], because He knows all things.

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.

We know that every person who has been [spiritually] conceived [by God and eventually born] does not continue in [a life of] sin, but God's one and only conceived [Son] keeps him [from continuing to sin], and the evil one [i.e., Satan] does not continue to touch him [i.e., continue to control his life].

But, if we live in the light [of righteousness] just like God [constantly] lives in the light [of righteousness], we can truly share a relationship with one another and [can know that] the blood of Jesus, God's Son, continues to cleanse [our spirits] from all of our sins.
