“Yet God repeatedly made known his intention to prevail finally over all the power of the Devil, and to destroy all his works, and set up his own kingdom and interest among men, and extend it as universally as Satan had extended his. It was for this purpose that the Messiah came and died, that God might be just, and the justifier of all that should believe in him. When he had laid down his life, and taken it up again, he sent forth his disciples to preach the good tidings to every creature, and to endeavour by all possible methods to bring over a lost world to God.”

“The most glorious works of grace that have ever took place, have been in answer to prayer; and it is in this way, we have the greatest reason to suppose, that the glorious out-pouring of the Spirit, which we expect at last, will be bestowed.”

“In one period the grossest ignorance and barbarism prevailed in the world; and afterwards, in a more enlightened age, the most daring infidelity, and contempt of God; so that the world which was once over-run with ignorance, now by wisdom knew not God, but changed the glory of the incorruptible God as much as in the most barbarous ages, into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things. Nay, as they increased in science and politeness, they ran into more abundant and extravagant idolatries.”

“As our blessed Lord has required us to pray that his kingdom may come, and his will be done on earth as it is in heaven, it becomes us not only to express our desires of that event by words, but to use every lawful method to spread the knowledge of his name. In order to this, it is necessary that we should become, in some measure acquainted with the religious state of the world; and as this is an object we should be prompted to pursue, not only by the gospel of our Redeemer, but even by the feelings of humanity, so an inclination to conscientious activity therein would form one of the strongest proofs that we are the subjects of grace, and partakers of that spirit of universal benevolence and genuine philanthropy, which appear so eminent in the character of God himself.”

“Our Lord Jesus Christ, a little before his departure, commissioned his apostles to Go, and teach all nations; or, as another evangelist expresses it, Go into all the world, and preach the gospel to every creature. This commission was as extensive as possible, and laid them under obligation to disperse themselves into every country of the habitable globe, and preach to all the inhabitants, without exception, or limitation. They accordingly went forth in obedience to the command, and the power of God evidently wrought with them.”
