The Word is God's voice not mans

It seems that there were some among the Thessalonians, as there must be amongst us, which did forsake all religion because the preachers did not agree, or because the lives of professors gave some offense; therefore Paul sheweth, that there is no cause why they should mislike the word for the preacher, or why they should despise religion for the professor, because the word and the religion are not theirs which teach it, and profess it, but God's. [Henry Smith]
