“When God is worshipped in any way other than that which He commands His jealousy is provoked, because the commandments of men (who say, “This is what we will do in worship”) are substituted for the doctrines and the commands of God. Sadly, man’s sinful heart is always more jealous to pursue its own designs than it is to obey God’s word. “Hence…our God and Savior has excluded from His Church every invention of man; has stamped upon every institution and ordinance the impress of His own sovereign authority. He has left us but the office and privilege of studying His Word, that we may ascertain His will, and then, follow it with a jealousy and vigilance like His own.” (Comin,3)
