"Sorry but there are billion people with their opinion reading their doctrine of devils does not profit me in anyway"
That's cool. But there's no need for me to continue this discussion then because the answers that guy gives in the link I gave, which are answers to some of the your questions you have asked in your posts, are pretty much the same as the answers I would give you, so whatever I say will be considered doctrine of devils to you as well. And I just don't have time to write it all out. That guy has written some thorough articles about the Sabbath, etc. and New vs. Old Covenant. These subjects really need to be thoroughly written out, otherwise we are just throwing scripture at one another and that doesn't really get anywhere.
But I have to ask you this. How is your doctrine working out for ya? Are you saved, and if so, why? Are you not saved, and if not, why not?
