We groan. See Barnes "Ro 8:22".

The sense is, that we are subjected to so many trials and afflictions in the present body; that the body is subjected to so many pains, and to so much suffering, as to make us earnestly desire to be invested with that body which shall be free from all susceptibility to suffering.

Earnestly desiring to be clothed upon with our house, etc. There is evidently here a change of the metaphor, which gives an apparent harshness to the construction. One idea of the apostle is, that the body here, and the spiritual body hereafter, is a house or a dwelling. Here he speaks of it as a garment which may be put on or laid off; and of himself as earnestly desiring to put on the immortal clothing or vestment which was in heaven. Both these figures are common in ancient writings; and a change in this manner in the popular style is not unusual. The Pythagoreans compared the body to a tent or hut for the soul; the Platonists liken it to a vestment. -- Bloomfield. The Jews speak of a vestment to the soul in this world and the next. They affirm that the soul had a covering when it was under the throne of God, and before it was clothed with the body. This vestment, they say, was "the image of God," which was lost by Adam. After the fall, they say, Adam and all his posterity were regarded as naked. In the future world they say the good will be clothed with a vestment for the soul, which they speak of as lucid and radiant, and such as no one on earth can attain. -- Schoettgen. But there is no reason to think that Paul referred to any such trifles as the Jews have believed on this subject. He evidently regarded man as composed of body and soul. The soul was the more important part, and the body constituted its mere habitation or dwelling. Yet a body was essential to the idea of the complete man; and since this was frail and dying; he looked forward to a union with the body that should be eternal in the heavens, as a more desirable and perfect habitation of the soul. Mr. Locke has given an interpretation of this in which he is probably alone, but which has so much appearance of plausibility that it is not improper to refer to it. He supposes that this whole passage has reference to the fact that at the coming of the Redeemer the body will be changed without experiencing death, (comp.1 Co 15:51,52;) that Paul expected that this might soon occur; and that he earnestly desired to undergo this transformation without experiencing the pains of dying. He therefore paraphrases it, "For in this tabernacle I groan, earnestly desiring, without putting off this mortal, earthly body by death, to have that celestial body superinduced, if so be the coming of Christ shall overtake me in this life, before I put off this body"

With our house. The phrase "to be clothed upon with our house" seems to be harsh and unusual. The sense is plain, however, that Paul desired to be invested with that pure, spiritual, and undecaying body which, was to be the eternal abode of his soul in heaven. That he speaks of as a house, (oikhthrion,) a more permanent and substantial dwelling than a tent, or tabernacle.
