Actually it is under the "Law" (TORAH) however, you are correct in that it is about lifestyle...you know like the SAME LAWS of THIS COUNTRY which we follow everyday we live with mostly NO QUESTIONS...
No i do not tithe. i am not under the law. You do not keep the law. you cannot not keep the hundreds of laws that isreal was ordered to keep . Do you live like an orthodox jew i dont think so.
do you have 2 kitchens, do you eat pprk, shrimp catfish I bet you do. do your menfolk cover their head in the santuary i bet they dont.
GRACE AND LAW ARE ONE IN THE SAME YOU CAN SAY...you can't have one without the other which means that "grace" is not NT or OT it's part of YAH's Character....Grace did not come with the death of a prophet (JC), it (grace) has always been...If not...OUR FOREFATHERS WOULD NOT HAVE ENTERED INTO THE LAND!!!!
FOR THEIR TO BE A problem with obedience to the scriptures would be to follow (your own ways).
