1. That we are not to suppose that the present enjoyments which believers experience in the highest degree, do fully come up to those that are reserved for them. There is a great difference as to the degree thereof. As a child that is newly born has something in common with what he shall have when arrived at a state of manhood; but there are several degrees, and other circumstances, in which he falls short of it: or, as a few drops are of the same nature with the whole collection of water in the ocean; yet there is a very small proportion between one and the other: so the brightest discovery of the glory of God, which we are capable of enjoying in this world; or the comfortable foretastes that believers have of heaven, fall very much short of that which they shall be possessed of, when they are received into it. And there are very great allays, and many things that tend to interrupt and abate their happiness, agreeably to the imperfection of this present state. Whatever grace they are enabled to act, though in an uncommon degree, is attended with a mixture of corruption; and as their graces are imperfect, so are the comforts that arise from thence, which are interwoven with many things very afflictive; so that they are not what they shall be, but are travelling through this wilderness to a better country, and exposed to many evils in their way thither. 2. All believers do not enjoy these delights and pleasures that some are favoured with in their way to heaven; the comforts, as well as the graces, of the Holy Spirit, are bestowed in a way of sovereignty, to some more, and to others less: Some have reason to say with the apostle, _Thanks be unto God, which always causeth us to triumph in Christ_, 2 Cor. ii. 14. others are filled with doubts concerning their interest in him, and go mourning after him all the day; and if they have, at some times a small glimpse of his glory, by which they conclude themselves to be, as it were, in the suburbs of heaven, they soon lose it, and find themselves to be in the valley of the shadow of death, as the disciples, when they were with Christ at his transfiguration, which was an emblem of the heavenly blessedness, when his _face did shine as the sun, and his raiment was white as the light_; which occasioned them to say, _it is good for us to be here_; before they had done speaking, or had time to reflect on their present enjoyment they were deprived of it when _the cloud overshadowed them_, Matt. xvii. 2,-5. so the believer is not to expect uninterrupted communion with God, or perfect fruition with him here. However, that which we are at present to consider, is that degree thereof which some enjoy; which is here called the first-fruits and earnest of glory. The scripture sets it forth under both these expressions.
