Hence it is, in the very highest degree, irrational for any one to rest for a single hour without a clear and settled assurance that he is truly converted to God. A converted soul has crossed the boundary line that separates the saved from the unsaved--the children of light from the children of darkness--the Church of God from this present evil world. The converted soul has death and judgment behind him, and glory before. He can be as sure of heaven as though he were already there; indeed as a man in Christ he belongs there already. He has a title without a blot, a prospect without a cloud. He knows Christ as his Saviour and Lord; God as his Father and Friend; the Holy Ghost as his blessed Comforter, Guide and Teacher; heaven as his bright and happy home. Oh! the unspeakable blessedness of being converted. Who can utter it? "Eye hath not seen, or ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love Him. But God hath revealed them unto us [believers] by His Spirit; for the Spirit searcheth all things, yea the deep things of God" (1 Cor. ii. 9, 10).
And now let us inquire what this conversion is, whereof we speak. Well, indeed, will it be for us to be divinely instructed as to this. An error here will prove disastrous in proportion to the interests at stake.
Many are the mistaken notions in reference to conversion. Indeed we might conclude, from the very fact of the vast importance of the subject, that the great enemy of our souls and of the Christ of God would seek, in every possible way, to plunge us into error respecting it. If he cannot succeed in keeping people in utter carelessness as to the subject of conversion, he will endeavour to blind their eyes as to its true nature. If, for example, a person has been roused, by some means or other, to a sense of the utter vanity and unsatisfactoriness of worldly amusements, and the urgent necessity of a change of life, the arch-deceiver will seek to persuade such an one to become religious, to busy himself with ordinances, rites and ceremonies, to give up balls and parties, theatres and concerts, drinking, gambling, hunting and horse-racing; in a word, to give up all sorts of gaiety and amusement, and engage in what is called a religious life, to be diligent in attending the public ordinances of religion, to read the Bible, say prayers, and give alms, to contribute to the support of the great religious and benevolent institutions of the country.
Now, this is not conversion. A person may do all this, and yet be wholly unconverted. A religious devotee whose whole life is spent in vigils, fastings, prayers, self-mortifications and alms deeds, may be as thoroughly unconverted, as far from the Kingdom of God as the thoughtless pleasure hunter, whose whole life is spent in the pursuit of objects as worthless as the withered leaf or the faded flower. The two characters, no doubt, differ widely--as widely perhaps, as any two could differ. But they are both unconverted, both outside the blessed circle of God's salvation, both in their sins. True, the one is engaged in "wicked works," and the other in "dead works;" they are both out of Christ; they are unsaved; they are on the way to hopeless, endless misery. The one, just as surely as the other, if not savingly converted, will find his portion in the lake that burneth with fire and brimstone.
Again, conversion is not a turning from one religious system to another. A man may turn from Judaism, Paganism, Mahometanism, or Popery, to Protestantism, and yet be wholly unconverted. No doubt, looked at from a social, moral, or intellectual standpoint, it is much better to be a Protestant than a Mahometan; but as regards our present thesis, they are both on one common platform, both unconverted. Of one, just as truly as the other, it can be said, unless he is converted, he cannot enter the Kingdom of God. Conversion is not joining a religious system, be that system ever so pure, ever so sound, ever so orthodox. A man may be a member of the most respectable religious body in Christendom, and yet be an unconverted, unsaved man, on his way to eternal perdition.
So also as to the theological creeds. A man may subscribe to any of the great standards of religious belief, the Thirty-nine Articles, the Westminster Confession, John Wesley's Sermons, Fox and Barclay, or any other creed, and yet be wholly unconverted, dead in trespasses and sins, and on his way to that place where a single ray of hope can never break in upon the awful gloom of eternity.
