Sin was introduced amongst the children of men by the fall of Adam, and has ever since been spreading its baneful influence. By changing its appearances to suit the circumstances of the times, it has grown up in ten thousand forms, and constantly counteracted the will and designs of God. One would have supposed that the remembrance of the deluge would have been transmitted from father to son, and have perpetually deterred mankind from transgressing the will of their Maker; but so blinded were they, that in the time of Abraham, gross wickedness prevailed wherever colonies were planted, and the iniquity of the Amorites was great, though not yet full. After this, idolatry spread more and more, till the seven devoted nations were cut off with the most signal marks of divine displeasure. Still, however, the progress of evil was not stopped, but the Israelites themselves too often joined with the rest of mankind against the God of Israel. 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. 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. They went forth according to their divine commission, and wonderful success attended their labours; the civilized greeks, and uncivilized barbarians, each yielded to the cross of Christ, and embraced it as the only way of salvation. Since the apostolic age many other attempts to spread the gospel have been made, which have been considerably successful, notwithstanding which a very considerable part of mankind are still involved in all the darkness of heathenism. Some attempts are still making, but they are inconsiderable in comparison of what might be done if the whole body of Christians entered heartily into the spirit of the divine command on this subject. Some think little about it, others are unacquainted with the state of the world, and others love their wealth better than the souls of their fellow-creatures.
