but if I wait long, that you may know how men ought to behave themselves in the house of God, which is the assembly of the living God, the pillar and ground of the truth.
      I. Those who are employed in the house of God must see to it that they behave themselves well, lest they bring reproach upon the house of God, and that worthy name by which they are called. Ministers ought to behave themselves well, and to look not only to their praying and preaching, but to their behaviour: their office binds them to their good behaviour, for any behaviour will not do in this case. Timothy must know how to behave himself, not only in the particular church where he was now appointed to reside for some time, but being an evangelist, and the apostle's substitute, he must learn how to behave himself in other churches, where he should in like manner be appointed to reside for some time; and therefore it is not the church of Ephesus, but the catholic church, which is here called the house of God, which is the church of the living God. Observe here, 1. God is the living God; he is the fountain of life, he is life in himself, and he gives life, breath, and all things to his creatures; in him we live, and move, and have our being, Acts 17:25; Acts 17:28. 2. The church is the house of God, he dwells there; the Lord has chosen Zion, to dwell there. "This is my rest, here will I dwell, for I have chosen it;" there may we see God's power and glory, Psalms 63:2.
