What would Paul have accomplished without the Holy Spirit's power?
The apostle Paul would have accomplished nothing apart from the Holy Spirit's power. The context explains that it is God who uses the man; Paul was a willing instrument, but his effectiveness came from the power of God, not from himself.
Les explains that even the apostle Paul, a willing instrument, would have accomplished nothing without the power of the Holy Spirit and the power of God. The glory belongs to the LORD because it is God who uses the man. Les says this is basic for every believer, including Sunday school teachers, television teachers, and those teaching classes in church or home. He then turns to Acts 16 and verse 14, the account of a certain woman named Lydia, as an example he has read often.
