For--proof of Co1 2:15, that the spiritual man "is judged of no man." In order to judge the spiritual man, the ordinary man must "know the mind of the Lord." But "who of ordinary men knows" that? that he may instruct him--that is, so as to be able to set Him right as His counsellor (quoted from Isa 40:13-14). So the Septuagint translates the Greek verb, which means to "prove," in Act 9:22. Natural men who judge spiritual men, living according to the mind of God ("We have the mind of Christ"), are virtually wishing to instruct God, and bring Him to another mind, as counsellors setting to right their king. we have the mind of Christ--in our degree of capability to apprehend it. Isa 40:13-14 refers to JEHOVAH: therefore, as it is applied here to Christ, He is Jehovah. Next: 1 Corinthians Chapter 3
