6. What a thorough concern then ought every Christian to feel, how hearty a care ought he to take for the obtaining and securing this his right and only end, the fruition of God? This our Saviour calls _The one thing needful_, in opposition to the many things that are apt to trouble and distract us in this busy life, which unless so far as they fall in with this, are all mere trifle and amusement. Even those affairs which carry the face of the greatest seriousness, and pretend to be of the weightiest consequence, if they are not so many parts of this, are _lighter than vanity and nothing_. For indeed a man has but one business in the world, and that is, to make sure his everlasting happiness, and to secure to himself the fruition of that excellent good, which is the true end of his being. This is the whole of man, his only considerable interest, and that upon which all depends. ’Tis not necessary, that he should be born to an estate, or that he should acquire one. ’Tis not necessary that he should succeed in his attempts, for this or that dignity or preferment; that he should live long to enjoy his wealth or greatness, or even that he should live at all. But it is absolutely necessary that he should arrive at his end, that he should attain to the fruition of God, whose loving-kindness is better than life, and without whom he cannot be happy. All the rest may be spared, but there is no dispensing with this. Should he lose all besides, and gain this one thing, yet still he would be happy. And should he gain all besides, and lose this one thing, yet still he would be miserable: for what gain will ever make amends for such a loss? Not that of the whole world, if we believe our Saviour: _What shall it profit a man, if he shall gain the whole world, and lose his own soul?_ Which is then only lost, when it loses God. ’Tis therefore one great part of the prudence of every Christian, after he has fixed this his right end, to endeavour, by much consideration, to possess his mind with a due sense of its moment and importance; and of what consequence it is, that he should succeed in this affair, whatever he miscarries in besides: which when he is once thoroughly convinced of, he will then diligently apply himself to the use of such means as are necessary thereto.
