Jesus said His command is not burdensome; i mean, He had to say that several times but still some think that we have to rest from His command?! The command to love one another is not even a burden at all. Trusting in the finished works of Jesus basically means to obey His commands which are not burdensome.
We don't obey so that we get saved but we obey so that we abide in salvation (Him) which came for everyone.
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.
