SECONDLY, If the command of Christ to teach all nations be confined to the apostles, then all such ordinary ministers who have endeavoured to carry the gospel to the heathens, have acted without a warrant, and run before they were sent. Yea, and though God has promised the most glorious things to the heathen world by sending his gospel to them, yet whoever goes first, or indeed at all, with that message, unless he have a new and special commission from heaven, must go without any authority for so doing. THIRDLY, If the command of Christ to teach all nations extend only to the apostles, then, doubtless, the promise of the divine presence in this work must be so limited; but this is worded in such a manner as expressly precludes such an idea. _Lo, I am with you always, to the end of the world._ That there are cases in which even a divine command may cease to be binding is admitted--As for instance, if it be _repealed_, as the ceremonial commandments of the jewish law; or if there be _no subjects_ in the world for the commanded act to be exercised upon, as in the law of septennial release, which might be dispensed with when there should be no poor in the land to have their debts forgiven. Deut. xv. 4. or if, in any particular instance, we can produce a _counter-revelation_, of equal authority with the original command, as when Paul and Silas were forbidden of the Holy Ghost to preach the word in Bythinia. Acts xvi. 6. 7. or if, in any case, there be a _natural impossibility_ of putting it in execution. It was not the duty of Paul to preach Christ to the inhabitants of Otaheite, because no such place was then discovered, nor had he any means of coming at them. But none of these things can be alledged by us in behalf of the neglect of the commission given by Christ. We cannot say that it is repealed, like the commands of the ceremonial law; nor can we plead that there are no objects for the command to be exercised upon. Alas! the far greater part of the world, as we shall see presently, are still covered with heathen darkness! Nor can we produce a counter-revelation, concerning any particular nation, like that to Paul and Silas, concerning Bythinia; and, if we could, it would not warrant our sitting still and neglecting all the other parts of the world; for Paul and Silas, when forbidden to preach to those heathens, went elsewhere, and preached to others. Neither can we alledge a natural impossibility in the case. It has been said that we ought not to force our way, but to wait for the openings, and leadings of Providence; but it might with equal propriety be answered in this case, neither ought we to neglect embracing those openings in providence which daily present themselves to us. What openings of providence do we wait for? We can neither expect to be transported into the heathen world without ordinary means, nor to be endowed with the gift of tongues, &c. when we arrive there. These would not be providential interpositions,
