The wisdom of God is so vast, so infinite, so wonderful that finite man lacks the capacity to even comprehend “the depth” and “unsearchable riches” of it on his own (cf. Rom. 11:33; Eph. 3:8). Even the most brilliant of intellects who has lived on this earth cannot compare with He who “knows all things” (1 John 3:20). God used these words to contrast His wisdom with the so-called “wisdom” of mankind: “‘For My thoughts are not your thoughts, Nor are your ways My ways,’ says the LORD. ‘For as the heavens are higher than the earth, So are My ways higher than your ways, And My thoughts than your thoughts’” (Isa. 55:8-9). Like David, we must stand in awe, saying, “Such knowledge is too wonderful for me; It is high, I cannot attain it” (Psa. 139:6).
Such being true, this statement of Paul is amazing, “We speak the wisdom of God” (1 Cor. 2:7). How could Paul (or any of the other apostles—“we”) speak the wisdom of God? As Paul asked in Romans 11:34, “For who has known the mind of the LORD?” How could God make any man to know His wisdom or even to speak His wisdom? And, can it be known today?
Paul had affirmed that the wisdom of God is deep (Rom. 11:33). In 1 Corinthians 2:10, he stated that “the Spirit searches all things, yes, the deep things of God.” So, this conclusion is found in the next verse, “No one knows the things of God except the Spirit of God” (v. 11).
The wisdom of God and the things of God had been hidden through the ages (2:7-8), but Paul said that “God has revealed them to us through His Spirit” (v. 10). Think about this. The wonderful wisdom of God, that had been hidden and not known by man, was revealed by God to His apostles. So, Paul affirms that what the apostles had “received…[these] things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words” (2:12-13, NASB).
The Holy Spirit revealed to the apostles the depths of the mind of God. The apostles, “moved by the Holy Spirit” (2 Pet. 1:21), wrote the words that are in New Testament, that we might with confidence receive and welcome “it not as the word of men, but as it is in truth, the word of God” (1 Thess. 2:13). Pick up your Bible! You have and can know the depth and wonder of the wisdom of God.
