(2.) To consider those types, which are called real, or things done, as being ordinances designed to signify the grace of the covenant. These were either occasional, or stated; the former whereof were designed for types, at those times, when the things were performed. But it doth not appear that they were so afterwards, in succeeding ages; as their _passing through the red sea_, being _under the cloud_, their _eating manna_ in the wilderness, and _drinking water_ that came _out of the rock_. All these things are expressly mentioned, by the apostle, as types, 1 Cor. x. 1, 3, 4. compared with ver. 11. and we may add thereto _the brazen serpent_, which was plainly a type of Christ, and, as such, our Saviour applies it to himself, in John iii. 14. But all these were occasional types, which were ordinances to the church no longer than the action was continued. Again, there were other things, which seemed to be standing types, or ordinances, in all successive ages, till Christ the Antitype came, as circumcision, the passover, sacrifices, and other rites of worship, used in the temple service; these things being expressly mentioned, in scripture, as types, we have ground to determine them to be so. Thus concerning the covenant of grace, as revealed to the church of old. 2. We are now to consider, that the method which God took in the administration of the covenant of grace, under the Old Testament, was sufficient to build up his elect in the faith of the promised Messiah. There were, indeed, many types given to the church, but these would not have led them into the knowledge of Christ, and salvation to be obtained by him, unless God had taken some method to explain them; for they had not a natural tendency to signify Christ, and the blessings of the covenant of grace, as words have, according to the common sense thereof, to make known the ideas they convey: but their signification was, for the most part, if not altogether, instituted, or annexed to them, by the divine appointment, and many of them had not the least resemblance, in themselves, of what they were ordained to signify; therefore it was necessary that they should be explained. For we may say the same thing of a type, that is said of a parable, as they are both figurative representations of some less known ideas, that are designed to be conveyed thereby; now a parable is styled, by the Psalmist, _A dark saying_, Psal. lxxviii. 2. and, by the prophet Ezekiel, _A riddle_, Ezek. xvii. 2. and our Saviour, speaking thereof, in this sense, tells his disciples, that _unto them it was given to know the mysteries of the kingdom of God, but to others in parables_, Luke viii. 10. and they are elsewhere opposed to a plain way of speaking, as when the disciples say, _Now speakest thou plainly, and speakest no proverb, or parable_, John xvi. 29. as it is rendered in the margin; so when Nathan reproved David for his sin, in the matter of Uriah, he first represented it by a
