MANY times we’ve heard “I’m under grace, not the “law.” I don’t have to do that (study & obey the Torah). To which we respond, then what do you do with 1 John 3:4? It’s in the NEW Testament and it says,

“Everyone who practices sin also practices lawlessness; and sin is lawlessness.”

Without the “law” (Torah) then there is NO SIN, because the Torah defines what sin IS. So, if you are not “under the law” then you are LAWLESS. According to Matthew 7 those believers who are lawless appear to be in danger for their eternal destination:

"Many will say to Me on that day, 'Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?' 

23 "And then I will declare to them, 'I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS.' 

Matt 7:22-23

Perhaps it would be wiser to rethink this doctrine and study further for answers. You might wish to check the article on this site entitled, What Does Lawlessness Mean in the New Testament?
