Πᾶς ὁ ποιῶν τὴν ἁμαρτίαν
everyone committing sin
καὶ τὴν ἀνομίαν ποιεῖ,
also lawlessness commits
καὶ ἡ ἁμαρτία ἐστὶν ἡ ἀνομία.
and sin is lawlessness
clearly, if you say you have no law, you are lawless and practicing sin.
just as clearly as 1 John 1:8-10 says you are a liar and The Truth is not in you if you say you are sinless.
however we who are in Him, are under the Law of Christ -- and we confess our sin, which He is faithful to forgive.
and if you deny your sin, and cover your iniquity, what does He do?
search it out.
in re: 1 John 3:4, kjv happens to have translated this very poorly, inserting interpretation that isn't faithful to the actual text.
compare Romans 2:23 --
you who boast in the Law, do you dishonor God by transgression of the Law?
παραβάσεως τοῦ νόμου
transgression of the Law
look at 1 John 3:4 as it was actually written - not in kjv, which was written by men, but in Greek, as the Holy Spirit gave it.
that phrase
παραβάσεως τοῦ νόμου is not present in it.
