So what is the proof that the Spirit is being poured out on us? The voice of the church rings with prophetic clarity. The people of God are no longer passive, intimidated, unresponsive, uncertain. They are no longer preoccupied with self, convenience, comfort.  They are no longer complaining, whining griping.  Instead they become outspoken in God's praise and gospel truth, 'declaring the wonders of God' (Acts 2:11).

From Ray Ortlund's book When God Comes To Church

What would happen within our local churches if we prayed?  What if we corporately gathered together frequently to confess our sins to God and to one another?  What if we prayed deeply and seriously for the Holy Spirit to move in our midst? What if we prayed for days and weeks and months for the advance of the gospel all around the world? What if we prayed, together, for the preaching of the Word and for the pastors whose ministries we sit under? What if we prayed for our own hearts to be open and humble and submissive to God’s Word? What if we quit worrying about what the culture or the world thinks about us and addressed ourselves to God and what He believes about us? What if we stopped trying to busy ourselves with more programs or more events or more stuff and just got back to simply, quietly, corporately praying and asking for the fresh winds of revival to blow through our midst? What if we simply, corporately, regularly started praying? What would God do? 

Father, 

By the power of the Holy Spirit enable us, whom you have appointed to this ministry of yours at all times and in all places to call on you without condemnation and without offense, with the testimony of a pure conscience; that you may hear us and be merciful to us, after the multitude of thy great goodness, for all glory, honor and worship befits you, the Father, the Son, and your Holy Spirit, now and for ever, and world without end.  Amen. 

John Chrysostom
