Isaiah 43:19 (ESV)
Behold, I am doing a new thing; now it springs forth, do you not perceive it? I will make a way in the wilderness and rivers in the desert.
This is a picture of a new Exodus that will take place or has taken place . We know that God again established Israel in 1947.
But God did a new thing when the Holy Spirit came at Pentecost. When the Holy Spirit comes in waves of revival we declare God is doing a new thing. It is a rediscovery of that personal relationship with God through Jesus Christ generated by the work of the Holy Spirit. When God goes to work personally, corporately, nationally it is a new thing.
