To illustrate this point, we observe: Enter some societies. Listen to the conversation which excites; notice the amusements which exhilarate--the pleasures which impart the greatest gladness. Might they not all exist in a world where the Son of God is unknown--where no need of him is felt, and no reference to him made? It could not be discovered from such social intercourse, that men are sinners, that they need a Saviour, or that there is one pressed on their acceptance by the God whom they have offended; nay, a single reference to these things would cast a cloud over the scene, would turn its mirth into muteness, and be regarded as an offence. FORBIDDEN INTERCOURSE. Now, wherever that is common, the earnest Christian cannot prosper; his soul must pine; it is deprived of what is to it like vital air, and plunged into an atmosphere of azote. There may be cases where duty compels some humble believer to witness such things, and at the sight his heart must be sore pained within him; but where the language of Canaan is not spoken, where the things of God are not relished, where He, the soul, and eternity do not obtain the prominence which heavenly wisdom has assigned to them, a child of God will not willingly go; he will never go of choice; duty may compel, but the feelings of the soul even in that case must be like those of the Jews by the rivers of Babylon, when they said, "How shall we sing the Lord's song in a foreign land?" Children are reared--friends are entertained--sometimes the dead are buried, amid unequivocal proofs that God is forgotten; and should not a believer in Jesus "flee these things?" LIKE ATTRACTS LIKE. Wherever we look in the wide domain of nature, we may notice that it is an universal law--Like attracts like. We do not find a timid bird associating with its natural enemy, a bird of prey. They fight.--We do not find the gentler animals seeking to associate with the beasts of prey.--We do not see the men of high civilization associating, in common life, with the savage or the gross--there is always something monstrous or unnatural where that universal law is outraged. Such a thing is commented on as a marvel, a departure from the established order of nature. Just as the fishes of the deep have their element, and the birds of the air have theirs, there is a broad unvarying line separating the different orders of creatures in the world which God has made.
