Before the time of Christ, we had people who believed in one God and people who didn't. When Christ was on earth, again we had those who believed in him and others who didn't. After Christ had come, we now clearly know that if we believe in him, we'll have eternal life; still the same division exists. Of course, that are also those who do not know about him yet. Anyway, God knows exactly how to judge each of us fairly. It's sad that we can be so self-centered and stubborn, preferring locking ourselves up in our own space, rather than opening up to God. If Christ is truly not our Lord and Savior, then Christianity has to be the biggest hoax in the entire history of mankind, fooling so many of us to die for him rather than giving up the faith. And you would have trouble explaining why even many more now experience freedom, peace, and joy in him. I believe we are divided, only because we are facing the true God.
