The farmer toils in the fields for a living, none of his works offend anyone. He knows nothing of where the end product of his work goes. He has no choice nor does he care, for none of it violates his conscience. The hens he dutifully raises, who lay the eggs which make the batter of that cake, carry on the life which God wills upon them; they serve their purpose in this world, they have no conscience of consequence, of right or wrong, of good or bad, or of sinfulness and righteousness. The couple in this bakery know what the Bible says about homosexuality, they have a sense of right and wrong, a sense of good or bad, a sense of sinfulness and righteousness.
The part of the farmer or the coop of chickens he raises is of no consequence. A non sequitur.
But the conscience of a man no longer matters. His beliefs are to be trampled underfoot with impunity, his sense of right and wrong judged summarily because he dares to have them. Who are you to judge the conscience of a man, or of any man, woman or child? Should you somehow come across the same dilemma this couple faced, expect no mercy from me, for you shewn none upon this couple or upon anyone who does likewise.
Speak and act as those who are going to be judged by the law that gives freedom, for judgment is without mercy to one who has shown no mercy. Mercy triumphs over judgment.
James 2:12-13
