But unto us God revealed them (hmin gar apekalupsen o qeo). So with gar B 37 Sah Cop read instead of de of Aleph A C D. "De is superficially easier; gar intrinsically better" (Findlay). Paul explains why this is no longer hidden, "for God revealed unto us" the wonders of grace pictured in verse Romans 9 . We do not have to wait for heaven to see them. Hence we can utter those things hidden from the eye, the ear, the heart of man. This revelation (apekalupsen, first aorist active indicative) took place, at "the entry of the Gospel into the world," not "when we were admitted into the Church, when we were baptized" as Lightfoot interprets it. Through the Spirit (dia tou pneumato). The Holy Spirit is the agent of this definite revelation of grace, a revelation with a definite beginning or advent (constative aorist), an unveiling by the Spirit where "human ability and research would not have sufficed" (Robertson and Plummer), "according to the revelation of the mystery" ( Romans 16:25 ), "the revelation given to Christians as an event that began a new epoch in the world's history" (Edwards). Searcheth all things (panta eraunai). This is the usual form from A.D. 1 on rather than the old ereunaw. The word occurs (Moulton and Milligan's Vocabulary) for a professional searcher's report and eraunhtai, searchers for customs officials. "The Spirit is the organ of understanding between man and God" (Findlay). So in Romans 8:27 we have this very verb eraunaw again of God's searching our hearts. The Holy Spirit not merely investigates us, but he searches "even the deep things of God" (kai ta baqh tou qeou). Profunda Dei (Vulgate). Cf. "the deep things of Satan" ( Revelation 2:24 ) and Paul's language in Romans 11:33 "Oh the depth of the riches and wisdom and knowledge of God." Paul's point is simply that the Holy Spirit fully comprehends the depth of God's nature and his plans of grace and so is fully competent to make the revelation here claimed.
