God pushes His mountain up from below. Christianity is not really a religion among religions, a mountain among the many mountains that reach to God. It is the end of religion, the end of mountain climbing, the end of all religious works designed to earn God's favor. God's favor is yours through the death of His Son. That's true, in a sense.
All religion leads to hell.
Only dying and rising in the death and resurrection of Jesus Christ leads to life with God. All nations will stream to God's mountain. The worship of Yahweh in the last days will pay no regard to race or ethnic background or language or nationality. It is the end multi-culturalism and ethnic or national religion. God is not a national god.
