For we that are in this tabernacle do groan,.... There are some of the saints who are not in the tabernacle, the body. They were in it, but now are not; their bodies are in the grave, the house appointed for all living; and their souls are in the house not made with hands, eternal in the heavens, in everlasting habitations, in the mansions prepared in Christ's Father's house; and they have done groaning, being delivered from every oppressor, sin, Satan, and the world; are at rest from all their labours, and ate free from every burden; only the saints who are in the tabernacle of the body, in an unsettled state, groan, being in the midst of tribulation, and not yet in the enjoyment of that happiness they are wishing for.
The reason of their groaning is, because they areburdened with the body itself, which is a clog and incumbrance to the soul in its spiritual exercises; and oftentimes by reason of its disorders and diseases a man becomes a burden to himself; but what the saints are mostly burdened with in this life, and which makes them groan the most, is the body of sin and death they carry about with them; the filth of it is nauseous, grievous, and intolerable; the guilt of it oftentimes lies very heavy on the conscience; the weight of it presses hard, and is a great hinderance to them in running their Christian race; nor have they any relief under this burden, but by looking to a sin bearing and sin atoning Saviour, the Lamb of God, who takes away the sin of the world.
They are also frequently burdened with Satan's temptations, with blasphemous thoughts, solicitations to sin, the fears of death, the pangs of it, and what will follow upon it; though God is faithful, who will not suffer them to be tempted above that they are able to bear; however, these temptations are great burdens, and occasion many a groan: to which may be added the various afflictions of life, which though comparatively "light", are in themselves heavy, grievous burdens, and hard to be bore; the nature, number, and continuance of them often make them so; and especially they are such, when God is pleased to hide his face, and withhold the discoveries of his love and mercy.
