And this is how we know [daily, by experience] that we have come to know Him [to understand Him and be more deeply acquainted with Him]: if we habitually keep [focused on His precepts and obey] His commandments (teachings).

And everyone who has this hope [confidently placed] in Him purifies himself, just as He is pure (holy, undefiled, guiltless).

We [who were with Him in person] have seen and testify [as eye-witnesses] that the Father has sent the Son to be the Savior of the world.

If anyone sees his brother committing a sin that does not lead to death, he will pray and ask [on the believer’s behalf] and God will for him give life to those whose sin is not leading to death. There is a sin that leads to death; I do not say that one should pray for this [kind of sin].

We know [for a fact] that we are of God, and the whole world [around us] lies in the power of the evil one [opposing God and His precepts].
