Paul, with his unfailing discernment, accepts it as a very possible contingency that a Christian man may do poor work. In that case, Paul says, the man will be saved as by fire; his work shall be burned, but himself be scatheless. He shall be in the position of a man whose house has been burnt; the man is saved, but his property, all that he has slowly gathered round him and valued as the fruit of his labour, is gone. He may have received no bodily injury, but he is so stripped that he scarcely knows himself, and the whole thought and toil of his life seem to have gone for nothing. So, says Paul, shall this and that man pass into the heavenly state, hearing behind him as he barely enters the crash of all he has been building up as it falls and leaves for the result of a laborious life a ghastly, charred ruin and a cloud of dust. To have been useless, to have advanced Christ's kingdom not at all, to have spent our life building up a pretentious erection which at last falls about our ears, to come to the end and find that not one solid brick in the whole fabric is of our laying, and that the world would have been quite as well without us--this must be humiliating indeed; but it is a humiliation which all selfish, worldly, and foolishly fussy Christians are preparing for themselves. To many Christians it seems enough that they be doing _something_. If only they are decently active, it concerns them little that their work is really effecting no good, as if they were active rather for the sake of keeping themselves warm in a chilling atmosphere than to accomplish any good purpose. Work done for this world must be such as will stand inspection and actually do the thing required. Christian work should not be less, but more, thorough. There is a degree of carelessness or malignity sometimes to be found in those who profess to be Christian teachers which Paul does not hesitate unconditionally to doom. "If any man destroy the temple of God, him shall God destroy." A teacher may in various ways incur this doom. He may in guiding some one to Christ fit him obliquely to the foundation, so that firm rest in Christ is never attained; but the man remains like a loose stone in a wall, unsettled himself and unsettling all around him. Any doctrine which turns the grace of God into licence incurs this doom. To lift stones from the mire they have been lying in and fit them into the temple is good and right, but to leave them uncleansed and unpolished is to disfigure the temple. Any teaching that does not recognise in Christianity the means of becoming holy, and encourages men to believe themselves Christians though they neither have nor wish to have the Spirit of Christ, destroys the temple.
