Re: the Trinity, still uncomprehensible in Its workings and physical/ethereal construction.
Context is very important in such thinking. COnsider the two verses often translated with “comprehension”.
Eph 3:16-21
(16) That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;
(17) That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
(18) May be able to comprehend with all saints what is the breadth, and length, and depth, and height;
(19) And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.
(20) Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,
(21) Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.
Compared with Job
Job 37:2-8
(2) Hear attentively the noise of his voice, and the sound that goeth out of his mouth.
(3) He directeth it under the whole heaven, and his lightning unto the ends of the earth.
(4) After it a voice roareth: he thundereth with the voice of his excellency; and he will not stay them when his voice is heard.
(5) God thundereth marvellously with his voice; great things doeth he, which we cannot comprehend.
(6) For he saith to the snow, Be thou on the earth; likewise to the small rain, and to the great rain of his strength.
(7) He sealeth up the hand of every man; that all men may know his work.
(8) Then the beasts go into dens, and remain in their places.
I still don’t see your point. Neither citation explains the workings of the Trinity. If anything, they explain that that particular knowledge is something beyond human need but by the power of the Holy Spirit you understand the things that are needful.
