What is the MYSTERY of that Body?
...God PURPOSED that body...IN Himself. (Heb 10:5)
A body hast thou prepared me - `thou didst fit for me a body.’ ’In thy counsels thou didst determine to make for me a body, to be a sacrificial victim’ (Wahl). In the Hebrew, Psa_40:6, it is "mine ears heat thou opened," or ’dug.’ Perhaps this alludes to boring the ear of a slave who volunteers to remain under his master when he might be free. Christ’s assuming a body, in order to die the death of a slave (Heb_2:14), was a voluntary submission to God’s service, like that of a slave suffering his ear to be bored by his master. His willing obedience to the Father’s will is what gave especial virtue to his sacrifice for man (Heb_10:7; Heb_10:9-10). The fitting of a body for him is not with a view to His incarnation merely, but to His expiatory sacrifice (Heb_10:10), as the contrast to "sacrifice and offering" requires: cf. also Rom_7:4; Eph_2:16; Col_1:22. More probably ’opened mine ears,’ means opened mine inward ear, to be obedient to what God wills me to do-namely, to assume the body He has prepared for my sacrifice. So Job, margin, Job_33:16; Job_36:10 (doubtless the boring of a slave’s ear symbolized such willing obedience); Isa_1:5, "The Lord God hath opened mine ear" - i:e., made me obediently attentive as a slave to his master. Others, ’Mine ears hast thou digged,’ or ’fashioned;’ not with allusion to Exo_21:6, but to the true office of the ear-a willing, submissive attention to God’s voice. The forming of the ear implies the preparation of the body; this secondary idea, really in the Hebrew, though less prominent is the one which Paul uses for his argument. As he obediently assumed the body prepared by the Father, in which to make his self-sacrifice, so ought we present our bodies a living sacrifice (Rom_12:1).

........just in case Ronald Bruno reads this......
But a body hast thou prepared me; or "fitted for me"; a real natural body, which stands for the whole human nature; and is carefully expressed, to show that the human nature is not a person. This was prepared, in the book of God's purposes and decrees, and in the council and covenant of grace; and was curiously formed by the Holy Ghost in time, for the second Person, the Son of God, to clothe himself with, as the Syriac version renders it, "thou hast clothed me with a body"; and that he might dwell in, and in it do the will of God, and perform the work of man's redemption: in Psa_40:6 it is, "mine ears thou hast opened"; digged or bored, the ear being put for the whole body; for if he had not had a body prepared, he could not have had ears opened: besides; the phrase is expressive of Christ's assuming the form of a servant, which was done by his being found in fashion as a man, Php_2:7 and of his being a voluntary servant, and of his cheerful obedience as such, the opening, or boring of the ear, was a sign, Exo_21:5. And thus by having a true body prepared for him, and a willing mind to offer it up, he became fit for sacrifice.

"But a body hast thou prepared me," (soma de katertiso moi) "But a body thou didst prepare for me,” or fitted me, in which he lived a sinless life, died a sinless death, except as he "bare our sins in his own body (the body of his flesh) on the tree," 1Ti_3:16; Gal_4:4-5; 1Pe_2:24; Col_1:20; Col_1:22; Eph_2:15-16; Heb_7:26.

Guess there is no mystery as to why a body was prepared for Christ Jesus
