Every person who practices a life of sin is also breaking [God's] law, for sin is law-breaking.

Here is how we can know what genuine love really is: It was [demonstrated by] Jesus laying down His life [on the cross] for us. And [because of that] we [too] should [be willing to] lay down our lives for [the sake of helping] our brothers [and sisters].

We [also] know that we are [children] of God and that the people of the whole world lie under [the control of] the evil one [i.e., Satan].
