No one can completely comprehend God (Romans 11:34), but through the guidance of the Holy Spirit, believers can understand spiritual truths. Believers have insight into some of God’s plans, thoughts, and actions because, with the Spirit within, they have access to the mind of Christ. Through the Holy Spirit, believers can begin to know God’s thoughts, talk with him, and expect his answers to their prayers. Paul could allow his detractors in Corinth to jeer at him, for they had no right to make judgments on him or his message—because he had the mind of Christ and they did not.
