See what is said on this subject in the preface to this epistle.
To serve the living and true God - The living God; in opposition to the idols, which were either inanimate stocks or stones, or the representations of dead men.
The true God - In opposition to the whole system of idolatry, which was false in the objects of its adoration, false in its pretensions, false in its promises, and false in all its prospects.
