Islam isn't the fastest growing religion in the world.
Islam is the second fastest growing religion.
Christianity is by far the fastest growing religion in the world.
"Tagging Christianity by an annual growth of approximately 2.6 million less Muslims than Christians. Approx. 1 million less due to slower population growth and approx. 1.5 million less due to fewer conversions to Islam than to Christianity."
As I have said before Christianity is not actually a religion. "The way to be right with God in every religion is by earning your way. It is based on works, not grace. Christianity is different from every religion in this aspect: all other religions (including Mormonism, Islam, Hinduism, and Buddhism) state that you must earn the right to be reconciled with God. It is by what you do in this life (good deeds or bad deeds) that determines your eternal destiny. Christianity is completely different from this. It is not religion.
'The difference between Christianity and every other faith in the world is that all other religions are about man trying to reach up to God. Christianity is about God reaching down to man.'
This is a very important distinction, and it is core to what I believe, so I would to clarify what that means you can go here: http://philippians1v21.wordpress.com/why-believe-i...
Religion is the creation of man and is not the intention or design of God.
That said, Islam is not a religion of peace as is becoming more and more apparent every day. No one is ever compelled to believe in Christianity. In Islam, and this is practiced throughout the world by Muslims under current laws in Islamic countries, the actual punishment for the apostate ranges from execution to prison term to no punishment. Islamic nations with sharia courts use civil code to void the Muslim apostate’s marriage and deny child custody rights, as well as his or her inheritance rights for apostasy.Twenty-three Muslim-majority countries, as of 2013, additionally covered apostasy in Islam through their CRIMINAL laws.
It is a crime to convert from Islam to any other religion punishable in many Muslim countries by death.
How can any religion that compels their believers, forces them under the penalty of death or at the least, conviction of a punishable crime, claim to be "growing". That sounds more like communism than a religion.
