In the desert, the Spirit is speaking. He spoke to Philip in Acts chapter 8. Verse 26, Now an angel of the Lord said to Philip, “Rise and go toward the south to the road that goes down from Jerusalem to Gaza.” This is a desert place…..8:29 And the Spirit said to Philip, “Go over and join this chariot.” The result of this glorious sovereign circumstance is that Christ is preached, taught and exalted. The person riding on the ancient vehicle learned about and was brought to Christ. The passage in Isaiah was used by the Spirit to exalt Christ. We should always trust the Spirit to bring circumstances for Christ to be made known.
