We are immersed in Satan's world. He has constant access to every servant of God through his fallen nature. His answer is given in Matt. Yet we are told today by neo-evangelicals that we should both teach and study in liberal universities and colleges of theology. There is one thing worse than division and that is peace with compromise .
Truth is infinitely more important than the false unity of the world.
Because for the sake of Truth, even families will be split with hostility so that at least someone within that unit can perpetuate God's Truth. If we honor and love the Lord Jesus we will watch for anything which may destroy His Truth. We will avoid such people. A good way of life or good doctrine is always contaminated by a bad environment or bad associations. A mere association of the good with the bad will never make the bad thing better.
