There will be a false unity in this world. Agree to disagree is how this one world religion will take place, under one head, and that will be the anti-christ. They will all come under one religion, because many people believe that we all serve the same God. The word of God says that He made the world in such a way, that everyone is without excuse. So even muslims, or anyone raised in a certain religion, is without excuse, and will answer to God on that Day. They worship mere men, but we worship the One God, through Christ, by the Spirit. Do not be deceived by fine sounding arguments. Christ did not come to bring peace, but a sword, nor did He come to make this world a better place, otherwise He would have become a king when His people tried to made Him one. The anti-christ will come, and will unite all the world religions together. It will seem very peaceful and good. But There is not true unity, except in Christ. Living by the Spirit. Dying to ourselves daily. There is none but Christianity, that teaches that a man came from heaven, sent by God, to die for our sins, that we commit daily. If we are offering our bodies to God, as we should, He gives us true peace and hope that does not compare to any other religion.
