The purified minds of Christians are to be stirred up, that they may be active and lively in the work of holiness. There will be scoffers in the last days, under the gospel, men who make light of sin, and mock at salvation by Jesus Christ. One very principal article of our faith refers to what only has a promise to rest upon, and scoffers will attack it till our Lord is come. They will not believe that he will come. Because they see no changes, therefore they fear not God, Psalm 55:19. What he never has done, they fancy he never can do, or never will do.
The Holy Spirit, both in the Old and the New Testament, spoke of a general turning from the faith of Christ, and the pure worship of God. This should come during the Christian dispensation, for those are called the latter days. False teachers forbid as evil what God has allowed, and command as a duty what he has left indifferent. We find exercise for watchfulness and self-denial, in attending to the requirements of God's law, without being tasked to imaginary duties, which reject what he has allowed. But nothing justifies an intemperate or improper use of things; and nothing will be good to us, unless we seek by prayer for the Lord's blessing upon it.
Even in gospel times there would be perilous times; on account of persecution from without, still more on account of corruptions within. Men love to gratify their own lusts, more than to please God and do their duty. When every man is eager for what he can get, and anxious to keep what he has, this makes men dangerous to one another. When men do not fear God, they will not regard man. When children are disobedient to their parents, that makes the times perilous. Men are unholy and without the fear of God, because unthankful for the mercies of God. We abuse God's gifts, if we make them the food and fuel of our lusts. Times are perilous also, when parents are without natural affection to children. And when men have no rule over their own spirits, but despise that which is good and to be honoured. God is to be loved above all; but a carnal mind, full of enmity against him, prefers any thing before him, especially carnal pleasure. A form of godliness is very different from the power; from such as are found to be hypocrites, real Christians must withdraw. Such persons have been found within the outward church, in every place, and at all times. There ever have been artful men, who, by pretences and flatteries, creep into the favour and confidence of those who are too easy of belief, ignorant, and fanciful. All must be ever learning to know the Lord; but these follow every new notion, yet never seek the truth as it is in Jesus. Like the Egyptian magicians, these were men of corrupt minds, prejudiced against the truth, and found to be quite without faith. Yet though the spirit of error may be let loose for a time, Satan can deceive the nations and the churches no further, and no longer, than God will permit.
