“Look therefore whether the light that is in you is not darkness.”
Thus all must consider themselves carefully, for sadly some may still think that their darkness is light (they have never known any other). The world is full of people who think that they have light when all they have is darkness. They have the light of reason, the light of lesser religion, the light of knowledge, but they do not have the true light. What they have may be relatively good, but they do not have the all important light. They boast in their light but they are blind. Indeed the test is simple. Is their light from the Lord? Is it the light of His word shining in their hearts? Do they hear His voice and follow Him (John 10:27-28)? Or is the light within them false light, the ‘light' which is Satan's imitation of true light (2 Corinthians 11:14)? Basically the question is do they hear and see His word and do it? If not the light is a false light, a pale reflection of light. It is darkness.
