2 Corinthians 2:5

That your faith should not stand in the wisdom of men, but in the power of God (KJV)

Then: This "in-your-face" statement flies through the air and whaps the detractors. Paul did all he did for the believers. It made no difference if they supported Paul or Apollos or Peter - or even declared themselves to be "Jesus" people. Their faith had to be cleaned up so no one put down anyone else or raised up one leader above another. How could the Corinthians do that? Stand in the power of God. Be sure that behaviors match that faith and not the unstable wisdom of men. All followers of Christ have his power to be wise. They can recognize and walk on the path of righteousness.

Now: Wisdom requires knowledge and power. Both come from the Lord by studying the Word, the examples of biblical characters, listening to the teachings of others and hearing the Holy Spirit speak to your heart. True then, true now.
