To manipulate and distort that truth, or to mix it with error, is to invite God’s eternal wrath. That’s why Paul told the Galatians, “If any man is preaching to you a gospel contrary to what you received, he is to be accursed!” (Galatians 1:9).
(John MacArthur – Grace To You) Any literal shepherd tasked with feeding and leading a flock of lambs would be thought deranged if he regarded wolves as potential pets to be domesticated and amalgamated into the fold. Suppose he actively sought and tried to befriend young wolves, presuming he could teach them to mingle with his sheep—insisting against all wise counsel that his experiment might succeed, and if it does, that the wolves will acquire the sheep’s gentleness and the sheep will learn beneficial things from the wolves….
Such a shepherd would be worse than useless; he himself would pose an extreme danger to the flock.
Nearly as bad would be a shepherd whose vision is myopic. He has never seen a wolf clearly with his own eyes. He therefore believes the threat of wolves is grossly exaggerated. Even though his sheep keep disappearing or getting torn to shreds by something, he refuses to believe that wolves are the ones harming his flock. He declares he is tired of hearing shrill wolf warnings from others. Finally concluding that people’s “negativity” toward wolves poses a greater danger to his flock than the wolves themselves, he takes out his reed and plays a gentle tune to lull the lambs to sleep.
