“These things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God.” (1 Corinthians 2:10, ESV)
Paul is making a philosophical argument in 1 Corinthians 2, and it is a striking one. He says that nobody knows what is in a man except the spirit of that man, in the same way that nobody knows what is in God except the Spirit of God. You cannot understand someone from the outside by analysis and observation alone. You need access to their interior. And the Spirit of God has interior access to God himself.
This is not a small statement. It means that when the Spirit speaks to you, he is not relaying second-hand information or surface-level description. He has searched the depths of God, the very deep things, and he brings those depths into your understanding. The wisdom you receive from the Spirit is not the wisdom of this age or of the rulers of this age, who are passing away (1 Corinthians 2:6). It is wisdom that comes from the interior of God himself.
Paul says this explains why the gospel looks like foolishness to people who do not have the Spirit. They are evaluating from the outside, using the tools available from the outside, and those tools cannot reach what is on the inside. A natural person does not accept the things of the Spirit of God (1 Corinthians 2:14). It is not primarily an intellectual failure. It is an access problem. You cannot read a room you have not been let into.
But you have been let in. The Spirit who searches everything, including the depths of God, has taken up residence in you. This means that when you read Scripture, you are not reading it alone. The Author is with you, and he has interior knowledge of what he wrote. When you pray, you have access to the Father’s own heart through the Spirit. When you face a decision, you are not reasoning from the outside in; you have the inside perspective available.
You have been given access that angels and scholars and philosophers do not automatically possess. The Spirit of God is in you, and he searches the depths of God on your behalf.
Prayer
Father, I am in awe of this: that the Spirit who knows your depths has made his home in me. I do not fully understand what I have been given, but I receive it today with gratitude. Holy Spirit, search the deep things of God on my behalf. Reveal to me what I need to know, what I cannot find by my own effort or intelligence. I want to know God deeply, not just accurately, and I know that depth comes from you. In the name of Jesus, Amen.
