There is another kind of faith, which has some things in common with saving faith, and is sometimes mistaken for it, but is vastly different from it. This, in some, is called an historical faith; and in others, by reason of the short continuance thereof, a temporary faith. An historical faith is that whereby persons are convinced of the truth of what is revealed in the gospel, though this has very little influence on their conversation: such have right notions of divine things, but do not entertain a suitable regard to them; religion with them is little more than a matter of speculation; they do not doubt concerning any of the important doctrines of the gospel, but are able and ready to defend them by proper arguments: nevertheless, though, in words, they profess their faith in Christ, in works they deny him: such as these the apostle intends when he says; Thou believest that there is one God, thou dost well; the devils also believe and tremble, James ii. 19. And he charges them with a vain presumption, in that they expected to be justified hereby; whereas their faith was without works, or those fruits which were necessary to justify, or evince its sincerity; or to prove that it was such a grace as accompanies salvation; and therefore he gives it no better a character than that of a dead faith.- Thomas Ridgley, A Body of Divinity, Volume 3, p. 124
As for that which is called a temporary faith, this differs little from the former, unless we consider it, as having a tendency, in some measure, to excite the affections; and so far to regulate the conversation, as that which is attended with a form of godliness, which continues as long as this comports with, or is subservient to their secular interest: but it is not such a faith as will enable them to pass through fiery trials, or part with all things for Christ's sake, or to rejoice in him, as their portion, when they meet with little but tribulation and persecution, in the world, for the sake of the gospel. This will evidently discover the insincerity thereof; for it will wither like a plant that is without a root: our Saviour speaks of it in the parable, of the seed that fell upon stony places, where they had not much earth, and forthwith they sprang up, because they had no deepness of earth; and when the sun was up, they were scorched; and because they had no root they withered away; which he explains of him, who heareth the word, and anon with joy, receiveth it; yet hath he not root in himself, but endureth for a while; for when tribulation or persecution ariseth, because of thy word, by and by he is offended, Matt. xiii. 5, 6. compared with ver. 20, 21. This parable had a particular relation to the Jews, who heard John the Baptist gladly, rejoicing in his light for a season; and seemed to be convinced, by his doctrine, concerning the Messiah, who was shortly to appear; but when they apprehended that his kingdom, instead of advancing them to great honors in the world, was like to expose them to tribulations and persecutions they were offended in him; and this is also applicable to all those who think themselves something, and are thought so by others, as to the profession they make of Christ and his gospel; but afterwards appear to be nothing, deceiving their own souls.
