That we are made in the image of God is to be taken literally. The body is part of our soul, and we are imperfect without it.
D&C 88:11-29
11 And the light which shineth, which giveth you light, is through him who enlighteneth your eyes, which is the same light that quickeneth your understandings;
12 Which light proceedeth forth from the presence of God to fill the immensity of space—
13 The light which is in all things, which giveth life to all things, which is the law by which all things are governed, even the power of God who sitteth upon his throne, who is in the bosom of eternity, who is in the midst of all things.
14 Now, verily I say unto you, that through the redemption which is made for you is brought to pass the resurrection from the dead.
15 And the spirit and the body are the soul of man.
16 And the resurrection from the dead is the redemption of the soul.
17 And the redemption of the soul is through him that quickeneth all things, in whose bosom it is decreed that the poor and the meek of the earth shall inherit it.
18 Therefore, it must needs be sanctified from all unrighteousness, that it may be prepared for the celestial glory;
19 For after it hath filled the measure of its creation, it shall be crowned with glory, even with the presence of God the Father;
20 That bodies who are of the celestial kingdom may possess it forever and ever; for, for this intent was it made and created, and for this intent are they sanctified.
21 And they who are not sanctified through the law which I have given unto you, even the law of Christ, must inherit another kingdom, even that of a terrestrial kingdom, or that of a telestial kingdom.
22 For he who is not able to abide the law of a celestial kingdom cannot abide a ccelestial glory.
23 And he who cannot abide the law of a terrestrial kingdom cannot abide a terrestrial glory.
24 And he who cannot abide the law of a telestial kingdom cannot abide a telestial glory; therefore he is not meet for a kingdom of glory. Therefore he must abide a kingdom which is not a kingdom of glory.
25 And again, verily I say unto you, the earth abideth the law of a celestial kingdom, for it filleth the measure of its creation, and transgresseth not the law—
26 Wherefore, it shall be sanctified; yea, notwithstanding it shall die, it shall be quickened again, and shall abide the power by which it is quickened, and the righteous shall inherit it.
27 For notwithstanding they die, they also shall rise again, a spiritual body.
28 They who are of a celestial spirit shall receive the same body which was a natural body; even ye shall receive your bodies, and your glory shall be that glory by which your bodies are quickened.
29 Ye who are quickened by a portion of the celestial bglory shall then receive of the same, even a fulness.
All living things shall receive an exaltation comparable to their obedience to the Laws they have received. As Christ, who is God, was ressurected, so shall we all be. A resurrection is not a metaphor, it is a reality.
