If we say we know him and don't keep his commandments WE ARE LIARS AND THE TRUTH ISNT IN US.
1 John 2:4 New International Version (NIV)
4 Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person.
So if someone is saying they know him and "doesnt keep his commandments" they are a liar and the truth is not in them.
if someone from OSAS says-
they know God but dont keep his commandments are they-
1."covered by the blood, forgiven for future sins etc",
2. Liars without the truth in them.
I am not trying to personally direct this in an offensive way, but in a way you might understand.
