1 Corinthians 2 talks about 2 kinds of wisdom, 2 kinds of spirits and 2 kinds of people. If you don't know Christ you can view God only through the lens of human worldly wisdom. The things of God can seem confusing and even foolish. If you know Christ, God's Spirit in you enables you to view God in a way your human spirit cannot. To understand His amazing grace and all He has given you!
