God dwells in unapproachable light. So it follows that His manifest presence is perceived in the likeness of fiery brilliance. As the Holy Spirit commences the promised New Covenant, the light of His presence and power shines forth, revealing the salvation of God to the nations. It is a most remarkable event. The Lord shines His face upon His remnant so that His way may be known on earth, His saving power among all nations! This is the definitive record of the miraculous gift of speaking in tongues, furnishing the only authoritative explanation of its meaning and purpose. It is supremely a light for the nations. The salvation of God in Christ Jesus is to reach to the end of the earth!
