2. A temple is remarkable for its _durability_. It is not like a tent, or a tabernacle, pitched for a short season, and then taken down. The materials which are used, and the manner of their construction, show that it will endure. The temples of antiquity were built for ages. Plutarch, when speaking of those of Athens, says, "Now they are old, they have the freshness of a modern building. A bloom is diffused over them which preserves their aspect untarnished by time, as if they were animated with a spirit of perpetual youth and unfading elegance." Those sacred structures, so familiar to the early Christians, stood unchanged while generations passed away. Time seemed to pass them by, while men and all their other works mouldered under his touch. How aptly does this suggest to us the imperishable nature of that work which the Holy Spirit carries on in the temple of the human soul. It is no ephemeral work. Every Christian coworking with God, is working for eternity. That soul which has become a temple, will stand the changes of time, and the floods of temptation. The world cannot demolish it. It is a work of grace. And where God has begun it, he will carry it on to the day of redemption. The durability of a temple also symbolizes the imperishable nature of the church, the great house which God is building in the world. It shall advance till the world shall end. Other institutions wear out. Colossal edifices of state totter and fall, and the wrecks of mighty dynasties lie strewn along the centuries. But while every thing else grows old, the church of God endures. The great house grows greater; spiritual builders are at work, in our own and in other lands, quarrying out new stones, and polishing them, and setting them in the walls. Many a time have its enemies battered it, and threatened to lay it in heaps; but the gates of hell have not prevailed against it; it endures; it still rises; column after column is added to it; it will rise till frieze and cornice and arch and dome are finished, and the top-stone shall be set with shoutings of Grace, grace unto it. The church, the great temple of God, shall stand. 3. The temples of antiquity were distinguished by their _beauty of proportion and perfection_. The Greeks and Romans employed the genius of their master artisans and their finest sculptors. All that the highest skill and taste and cultivation could do was profusely lavished on those immortal works of art; and the results produced were those models of architectural strength and symmetry which succeeding ages, with all their boasted progress, have not excelled. Unity of design, the adjustment of many parts in one harmonious whole, each part fitted to its appropriate place, with nothing left out and nothing superfluous, but all united to produce an impression of beauty and harmony on the mind of the beholder--these were the characteristic excellences of those grand old temples to which the apostle compares Christians in our text.
