The Muslims would implement Sharia Law, which would make Islam either obligatory or reduce non-Muslims to serfhood. In times past, Mohammed practiced conversion by the sword (convert or die). The Church of Christ does no such thing (or should not); it preaches the Gospel to one and all, particularly to heathens and pagans.

The Muslims are known today for their willingness to shed blood to settle matters of religious controversy (Shia vs. Sunni). There are nice people everywhere. Most Germans who voted for Hitler and joined the Nazi Party were nice people. Nice people are not the problem. They stand aside to let the nasty people have their way.

If you are not Jewish, understand that the Old Testament is no longer in effect. There is a difference between Law (condemnation) and Gospel (salvation). If you are a Christian you clearly know that Christ has redeemed you as a member of His church. By avoiding fellowship with other Christians you are turning your back on Christ. Remember what happened when Christ was "on the road," preaching to who would listen? If he came to a place that refused him, he would shake off the dust from his sandals and leave. You turn your back on Christ and he can reciprocate, as you wish it. Don't fool yourself that "reading the Bible" is following his injunction. That's just a make-believe.

Discord in the church is regrettable and, sadly, impossible to prevent among sinful human beings. (I have had some bitter experiences myself.) But it only means that one must persist in finding a church that can become a home and family in Christ. When you are seeking Christ, you...don't...give...up.
