Why do some Christians believe God's law was abolished?

christians change their laws all the time to better fit their needs they are not worshipping god they are worshipping themselves but also having god as their example. They are afraid of burning in an inferno so they all seek some kind of paradise. Take away the hell and the Satan stereotypes and no one would follow god which means no one really loves god and only do because they believe they will and want to go to a heaven which is really a selfish thought if you think about it. That is why I follow my Dark Art because I don't have to lie to myself and I can truly be true to myself.
