Many are out there who call themselves Christians whereas they are not , many just run under the cover of Christians , they just use Christian name as cover they are not real Christians. It's not possible we have different beliefs while we have the same God, it's not true we have the same God, calling oneself a christians when one didn't follow the rules of Christ. We just call ourselves Christian sometimes which they are not, as a true Christian ,you must follow the rules of Christ wholeheartedly.
Disobeying God's rule will not bring profit or merit to you, putting aside one God's word is not Worth to be called a Christian, a Christian follow each and every word of God, without letting go of any word, without putting aside some rules . We read in the scripture which says As a Christian we must obey all things whatsoever He has commanded us to do, all what Comes out of His mouth.
As a Christian, we are taught all we have to do, which is the commandments of God which one of these commandments is to refuse idolatry.The question , why do we now have different beliefs when we have one God? The all so Christians have the same God, bcos in the scripture Mathew 4:8 said why serve god but by nature they are not god. He told us not to believe in idols,not to believe they even have a part or a pinch of divinity.
We ought not to think that those silver ,gold and stone graven by man. So, you can't call them Christian , the way of the Bible , they are not Christians, they are unchristian. Just like having a host of wives are unchristian because God only appoint minister to have only one wife .
Those that believe in the Bible, will not do things contrary to the word of God.
