The Holy Spirit today?
John Piper summarized his position on the work of the Holy Spirit in a sermon which is freely available in text, audio and video from Desiring God.
“Should we be expecting the same miraculous confirmations of our witnessing [evangelism] today? My answer is yes, but not in the same measure that the apostles experienced this miraculous power. The reason I say yes is that I don’t see any compelling reason given in the New Testament that God has declared a moratorium on miracles. But I do see lists of miraculous gifts for the church (not just apostles) in 1 Corinthians 12:8-10. So I think God intends to bless his word and his people with miracles in our day — extraordinary works of divine power that go beyond the laws of nature.
… when the Lord Jesus returns to heaven and the apostles have laid the foundation of the church in the New Testament and are taken off the scene, I think what we have is not a de-supernatualized religion. Not at all! The Holy Spirit has been poured out, and he is still fully capable of doing signs and wonders. Rather, we have a centralized focus on the word of God, the gospel, because all the central acts of salvation are now in history and it is the word that connects us with these saving acts of God in the past.
… As long as we keep the word of God in its properly central place, I think it would please the Lord for us to pray the way the early church did in Acts 4:29-30. Here’s what they said, “And now, Lord, look upon their threats and grant to your servants to continue to speak your word with all boldness, while you stretch out your hand to heal, and signs and wonders are performed through the name of your holy servant Jesus.” We don’t dictate when or what kind or how many miracles God may do among us. But not to ask for them seems to me to be more secularistic and naturalistic than biblical.”
