There is, today, a move away from the deep endearing knowledge of God and what He wants us to know. We are shallow in knowledge, relationship and living. We can no longer call our selves Christians because we do not pass the test of "Christ like." We want what we want and tend to move through the buffet line of the Bible, picking and choosing our desires. By this we allow our selves to indulge in worldly thought and actions.
We are called to be a separate people, distinct from the world and its practices. Those that call themselves Christians today practice worldly things and are no longer identifiable as Christians.
