"What no eye has seen, what no ear has heard, and what no human mind has conceived, the things God has prepared for those who love him, these are the things God has revealed to us by his Spirit." (1 Corinthians 2:9-10)
Paul reminds the Corinthians of how he came to them: not with eloquence or superior wisdom, but in weakness and fear and much trembling. He resolved to know nothing among them except Jesus Christ and him crucified. The message and the preaching were not with persuasive words of human wisdom but with a demonstration of the Spirit's power, so that their faith might rest not on human wisdom but on God's power. This deliberate renunciation of rhetorical excellence, in a city that prized such excellence above almost everything, is itself a form of the Gospel: the message about a crucified God cannot be delivered by a triumphant orator without contradiction.
But there is a wisdom Paul does speak among the mature, a wisdom not of this age or of the rulers of this age who are passing away. It is God's secret wisdom, hidden and destined for our glory before time began. The rulers of this age did not understand it; if they had, they would not have crucified the Lord of glory. Then Paul quotes from Isaiah, adapted: What no eye has seen, what no ear has heard, and what no human mind has conceived, the things God has prepared for those who love him, these are the things God has revealed to us by his Spirit. The revelation of what no human faculty could attain comes exclusively through the Spirit. The Catechism calls this the reason why faith is always a gift: what God reveals in Christ exceeds every natural human capacity for knowing (CCC 36).
The Spirit searches all things, even the deep things of God. No one knows the thoughts of God except the Spirit of God, just as no one knows the thoughts of a person except that person's own spirit. The spiritual person is able to judge all things but is not subject to merely human judgment, for who has known the mind of the Lord so as to instruct him? But we have the mind of Christ. This extraordinary claim, that the believer who has received the Spirit has access to the mind of Christ, is the theological foundation of all Christian discernment: the Spirit who dwells in the baptised is the same Spirit who searches the depths of God.
Brothers and sisters, Paul came to Corinth in weakness and fear and trembling, and in that weakness the Spirit demonstrated his power. The invitation is the same for us: stop trying to be impressive and start being available. The Spirit does not need our strength. He needs our surrender. Come to God in your weakness today and watch what the demonstration of the Spirit looks like when human performance gets out of the way.
Lord God, what no eye has seen or ear heard you have revealed to us by your Spirit. Give us the mind of Christ. Let our faith rest not on human wisdom but on your power. And let our weakness be the very space in which your Spirit demonstrates what no rhetoric could accomplish. Through Christ our Lord. Amen.
