1 Corinthians 2:10-12 - "God has revealed these things to us through the Spirit. The Spirit searches everything, including the depths of God. Who knows a person's depths except their own spirit that lives in them? In the same way, no one has known the depths of God except God's Spirit. We haven't received the world's spirit but God's Spirit so that we can know the things given to us by God."
Proverbs 14:10 - "The heart knows its own distress; another person can't share its joy."
