4. Many eminent men have spoken thus: have advised us “To cease from all outward actions;” wholly to withdraw from the world; to leave the body behind us; to abstract ourselves from all sensible things: to have no concern at all about outward religion, but to “work all virtues in the will,” as the far more excellent way, more perfective of the soul, as well as more acceptable to God. 5. It needed not that any should tell our Lord, of this master-piece of the wisdom from beneath! This fairest of all the devices wherewith _Satan_ hath ever perverted the right ways of the Lord. And O! What instruments hath he found from time to time, to employ in this his service! To wield this grand engine of hell, against some of the most important truths of God! Men that _would deceive if it were possible the very elect_; the men of faith and love: yea, that have for a season deceived and led away no inconsiderable number of them; who have fallen in all ages into the gilded snare, and hardly escaped with the skin of their teeth. 6. But has our Lord been wanting on his part? Has he not sufficiently guarded us against this pleasing delusion? Has he not armed us here with armour of proof against Satan _transformed into an angel of light_? Yea, verily: he here defends, in the clearest and strongest manner, the active, patient religion he had just described: what can be fuller and plainer than the words he immediately subjoins, to what he had said of doing and suffering? _Ye are the salt of the earth. But if the salt have lost its savour, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out and trodden under foot of men. Ye are the light of the world: a city that is set on an hill cannot be hid. Neither do men light a candle and put it under a bushel; but on a candlestick and it giveth light to all that are in the house. Let your light so shine before men that they may see your good works and glorify your Father which is in heaven._ In order fully to explain and inforce these important words, I shall endeavour to shew, First, That Christianity is essentially a social religion, and that to turn it into a solitary one, is to destroy it: secondly, That to conceal this religion is impossible, as well as utterly contrary to the design of its Author. I shall, thirdly, Answer some objections; and conclude the whole with a practical application. I. 1. First. I shall endeavour to shew, that Christianity is essentially a social religion; and that to turn it into a solitary religion, is indeed to destroy it.
