But God hath revealed them unto us. — Here the emphatic word is “us.” The latter part of 1 Corinthians 2:8-9 are parenthetical, and the sense goes back to the beginning of 1 Corinthians 2:8. “None of the princes of this age know these things, but God hath revealed them unto us His apostles and teachers” (Matthew 13:11; Matthew 16:17; 2 Corinthians 12:1). This revelation of spiritual truth is made by the Holy Spirit of God to our spirits (Romans 8:16). The Apostle gives two proofs that the Apostles have this knowledge, and that the Holy Spirit is the source of it: 1. (1 Corinthians 2:10-11), because the Holy Spirit alone is capable of imparting this knowledge; and 2. (1 Corinthians 2:12-16), because the Holy Spirit has been given to us the Apostles.
Searcheth all things. — The word “searcheth” here does not convey the idea of inquiry for the purpose of acquiring knowledge, but rather complete and accurate knowledge itself, as in Romans 8:27; see also Psalms 139:1.
