As God can send a nation or people no greater blessing than to give them faithful, sincere, and upright ministers, so the greatest curse that God can possibly send upon a people in this world is to give them over to blind, unregenerate, carnal, lukewarm, and unskilful guides. And yet, in all ages, we find that there have been many wolves in sheep's clothing, many that daubed with untempered mortar, that prophesied smoother things than God did allow. As it was formerly, so it is now; there are many that corrupt the word of God and deal deceitfully with it.
