It’s true that Christ was nailed to the cross in weakness, but now he’s alive by God’s power. In the same way, we share his weakness, but by God’s power we’ll be alive with Christ as we deal with you.
God wisely planned that the world wouldn’t be able to understand him through its own wisdom. Instead, God was happy to use the foolish things we preach to save those who believe.
The person who doesn’t have the Spirit doesn’t accept the things that come from the Spirit of God. Those things seem foolish to them, and they can’t understand them, because they can’t be understood without the Spirit’s help.
