The message of the gospel is truth accompanied by experienced reality (as in 1 Corinthians 2:1-5). Although it came in word (proclaimed truth), it did not come in word alone: God verified its truthfulness by a display of His power through the ministry of the Holy Spirit. Paul’s Spirit-empowered word was regularly accompanied by Spirit-empowered miracles as well (Romans 15:18-19). Galatians 3:1-5 shows that Paul’s converts’ own experience of the Spirit was also accompanied by experiential phenomena to which Paul can appeal as evidence of their having become the children of God by faith. It is this difference between Paul and us that is so radical that it explains a lot about our present condition in the West. We need to get back to Biblical Christianity and live like Jesus called us to live by the Holy Spirit!
