In connection wit (1) & (2) the phrase “the word of the Lord”, ie the revealed will of God (very frequent in the OT), is used of a direct revelation given by Christ (refs); in this respect it is the message from the Lord, delivered with his authority and made effective by his power; (c) discourse, speech, of instruction, etc (refs).
(II) The Personal Word, a title of the Son of God… eclaring (1) His distinct and superfinite Personality, (2) His relation in the Godhead, (3) His Deity; in Jn 1:3 his creative power; in v14 his incarnation…
Young’s Concordance:
OT Heb: Mind (= heart. leb, seat of intellect) - used of God eg Jer 19:5, 32:15.
Mind (= mouth, peh) Lev 24:12
Mind (= spirit, ruach) used of human mind Gen 26:35; Prov: 29:11; Eze 11:5, 20:32; Dan 5:20, Hab 1:11, but often of the spirit/mind (NIV) of God, eg Isa 40:13 (in context of creation).
NT equivalent is “νους” (used of mind of God Rom 11:34 = counsels, purpose).
I think that to speak of the mind of God is unproblematic and completely orthodox - the Fathers regularly spoke of creation as conceived in God’s mind, expressed through Christ the Word, and executed by the Spirit.
I think the thought in Scripture - an in historical theology - is that whilst one speaks only analogously of any “part” of God, it’s not that “mind” is a mundane concept applied to God, but that “mind” is a supernatural endowment given to man.
