To me, though I am the very least of all the saints, this grace was given, to preach to the Gentiles the unsearchable riches of Christ, and to bring to light for everyone what is the plan of the mystery hidden for ages in God, who created all things, so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places.
(Eph. 3:8-10)(ESV)
The apostle Paul wrote to the Corinthian Christians that "the world did not know God through wisdom"(1 Cor. 1:21)(CSB). The philosophy of the Greeks never revealed God, and the religions of men cannot find Him. Zophar, the friend of Job, asked him a question, "Can you fathom the depths of God or discover the limits of the Almighty?"(Job 11:7)(CSB). The obvious answer was "No". God has made foolish the wisdom of this world as men seek to discover Him through their knowledge and learning. (1 Cor. 1:20).
God's wisdom is a Person, the Lord Jesus Christ. He has been made unto us wisdom (1 Cor. 1:30); and in Him are all the treasures of wisdom and knowledge hidden (Col. 2:3). However, the specific way in which God's wisdom is revealed is in the crucifixion and resurrection of Jesus Christ. This is God's way of dealing with the world's sin and making people fit for His presence.
To the Jew this is a stumbling block while to the educated Gentile it is foolishness (1 Cor. 1:18,23), but to those who are saved it is the power and wisdom of God (1 Cor. 1:18,24).
The true church is composed of all who have accepted the Lord Jesus as God's Son and their Savior. They have been baptized into the body of Christ (1 Cor. 12:13; Eph. 1:22,23).
Through this body God is making known His wisdom to the angelic realm. The church is the intermediate agency. As angels watch the growth of the church they are learning about God's wisdom. Are they learning anything from you and me? This is a searching question.
