{26} Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.

(26) Secondly, he wills the order of this twofold state or quality to be observed, that the natural was first, Adam being created of the clay of the earth. And the spiritual follows and came upon it, that is, when the Lord being sent from heaven, endued our flesh, which was prepared and made fit for him, with the fulness of the Godhead.

People's New Testament

15:46 Howbeit that was not first which is spiritual. The first Adam came before the second Adam.

But that which is natural. The natural body which proceeds from the first Adam is our tabernacle first.

Afterward that which is spiritual. After this life comes the spiritual body, which the second Adam gives.

Jamieson-Fausset-Brown Bible Commentary

46. afterward-Adam had a soul not necessarily mortal, as it afterwards became by sin, but "a living soul," and destined to live for ever, if he had eaten of the tree of life (Ge 3:22); still his body was but an animal-souled body, not a spiritual body, such as believers shall have; much less was he a "life-giving spirit," as Christ. His soul had the germ of the Spirit, rather than the fulness of it, such as man shall have when restored "body, soul, and spirit," by the second Adam (1Th 5:23). As the first and lower Adam came before the second and heavenly Adam, so the animal-souled body comes first, and must die before it be changed into the spiritual body (that is, that in which the Spirit predominates over the animal soul).

Matthew Henry's Concise Commentary

15:35-50 1. How are the dead raised up? that is, by what means? How can they be raised? 2. As to the bodies which shall rise. Will it be with the like shape, and form, and stature, and members, and qualities? The former objection is that of those who opposed the doctrine, the latter of curious doubters. To the first the answer is, This was to be brought about by Divine power; that power which all may see does somewhat like it, year after year, in the death and revival of the corn. It is foolish to question the Almighty power of God to raise the dead, when we see it every day quickening and reviving things that are dead. To the second inquiry; The grain undergoes a great change; and so will the dead, when they rise and live again. The seed dies, though a part of it springs into new life, though how it is we cannot fully understand. The works of creation and providence daily teach us to be humble, as well as to admire the Creator's wisdom and goodness. There is a great variety among other bodies, as there is among plants. There is a variety of glory among heavenly bodies. The bodies of the dead, when they rise, will be fitted for the heavenly bodies. The bodies of the dead, when they rise, will be fitted for the heavenly state; and there will be a variety of glories among them. Burying the dead, is like committing seed to the earth, that it may spring out of it again. Nothing is more loathsome than a dead body. But believers shall at the resurrection have bodies, made fit to be for ever united with spirits made perfect. To God all things are possible. He is the Author and Source of spiritual life and holiness, unto all his people, by the supply of his Holy Spirit to the soul; and he will also quicken and change the body by his Spirit. The dead in Christ shall not only rise, but shall rise thus gloriously changed. The bodies of the saints, when they rise again, will be changed. They will be then glorious and spiritual bodies, fitted to the heavenly world and state, where they are ever afterwards to dwell. The human body in its present form, and with its wants and weaknesses, cannot enter or enjoy the kingdom of God. Then let us not sow to the flesh, of which we can only reap corruption. And the body follows the state of the soul. He, therefore, who neglects the life of the soul, casts away his present good; he who refuses to live to God, squanders all he has.
