What the number of these laws was, we know not; but, as there have been, in all ages, various positive laws relating to instituted worship, doubtless, Adam had many such laws revealed to him though not mentioned in scripture. This I cannot but observe, because some persons use such modes of speaking about this matter, as though there were no other positive law, that man was obliged to obey but that of his not eating of the tree of knowledge of good and evil, or, together with it, that which related to the observation of the sabbath.[48] 4. The obedience, which man was to perform, was to be perpetual; by which we are not to understand, that it was to be performed to eternity, under the notion of a condition of the covenant, though it certainly was, as this covenant contained in it the obligation of a law. The reason of this is very obvious; for, when any thing is performed, as a condition of obtaining a subsequent blessing it is supposed that this blessing is not to be conferred till the condition is performed. But that is inconsistent with the eternal duration of this obedience, on the performance whereof the heavenly blessedness was to be conferred; and therefore, though divines often use the word _perpetual_, when treating on this subject, it must be understood with this limitation, that man was to obey, without any interruption or defect, so long as he remained in a state of probation; and this obedience had a peculiar reference to the dispensation, as it was federal: but, when this state of trial was over, and the blessing, promised on this condition, conferred, then, though the same obedience was to be performed to eternity, it would not be considered as the condition of a covenant, but as the obligation of a law. And this leads us to enquire, Whether we may not, with some degree of probability, without being guilty of a sinful curiosity, determine any thing relating to the time of man’s continuance in a state of trial, before the blessing promised, at least, that part of it, which consisted in the grace of confirmation, would have been conferred upon him. Though I would not enter into any subject that is over-curious, or pretend to determine that which is altogether uncertain, yet, I think this is not to be reckoned so, especially if we be not too peremptory, or exceed the bounds of modesty, in what respects this matter. All that I shall say, concerning it, is, that it seems very probable that our first parents would have continued no longer in this state of probation, but would have attained the grace of confirmation, which is a considerable circumstance in the blessing promised in this covenant, as soon as they had children arrived to an age capable of obeying, or sinning, themselves, which, how long that would have been, it is a vain thing to pretend to determine.
