Will the outpouring of wisdom and prudence on the Church Age ever happen again?
No. The wisdom and prudence poured out on Church Age believers is unique: it had never happened before, and it will never happen again once the Church is done. Church Age believers stand on separate, special ground, so this outpouring will not be repeated after the Church is complete.
Les explains that by God's grace, Church Age believers have wisdom and prudence poured out on them in a way that has never happened before. He says it will not happen again once the Church is done. This places Church Age believers on separate, special ground. The surrounding context contrasts this unique Church Age outpouring with Old Testament prophecy that was not secret, and with Peter and Jesus, who dealt with Israel and the prophetic rather than the Body of Christ.
