A black and white TV is actually grey
It's my understanding that black and white television is made up of thousands of entirely black and entirely white dots which I think goes more towards proving the truth of the absolute and singular intent of God. Life really is black and white, however much we perceive the grey tones.
Now, none of us is 100% correct, I grant you that. But certainly some are closer to the truth than others. God commands us to preach Christ risen with as much clarity and resolve as He gives to us.
The intensity of the beam created the shades.
Nevertheless, bright phosphors adjacent to unlit phosphors made them appear black when they were actually yellow-blue (grey). That was my point.
Anyway, I do agree that life is black and white, good and evil, right and wrong, truth and lie.
But only God knows objective Truth - we cannot seek Truth through reason alone (much to the chagrin of the Greeks according to Paul) --- but rather must receive His revelations to us through Jesus Christ, the Holy Spirit, Scriptures and Creation. Spiritual knowledge is foolishness to the natural man.
