Because of this, God sends them a working of error, that they should believe a lie;
      I. A general apostasy, there would come a falling away first,2 Thessalonians 2:3; 2 Thessalonians 2:3. By this apostasy we are not to understand a defection in the state, or from civil government, but in spiritual or religious matters, from sound doctrine, instituted worship and church government, and a holy life. The apostle speaks of some very great apostasy, not only of some converted Jews or Gentiles, but such as should be very general, though gradual, and should give occasion to the revelation of rise of antichrist, that man of sin. This, he says (2 Thessalonians 2:5; 2 Thessalonians 2:5), he had told them of when he was with them, with design, no doubt, that they should not take offence nor be stumbled at it. And let us observe that no sooner was Christianity planted and rooted in the world than there began to be a defection in the Christian church. It was so in the Old-Testament church; presently after any considerable advance made in religion there followed a defection: soon after the promise there was revolting; for example, soon after men began to call upon the name of the Lord all flesh corrupted their way,--soon after the covenant with Noah the Babel-builders bade defiance to heaven,--soon after the covenant with Abraham his seed degenerated in Egypt,--soon after the Israelites were planted in Canaan, when the first generation was worn off, they forsook God and served Baal,--soon after God's covenant with David his seed revolted, and served other gods,--soon after the return out of captivity there was a general decay of piety, as appears by the story of Ezra and Nehemiah; and therefore it was no strange thing that after the planting of Christianity there should come a falling away.
