John 3:8 KJV
The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
My wife and I were watching the game show Jeopardy a week or so ago when one of the contestants was introduced as a scientist. He worked on the Eastern Seaboard of the United States studying hurricanes. He speculated that if they could understand a hurricane, perhaps they could control its impact. Alex asked "Do you understand hurricanes?" to which this scientist quickly and authoritatively answered, "No!" Even with all of our advancements, we still do not know "whence it cometh and whither it goeth."
The same is true of the spiritual life. The new birth is work that God does. Men would love to know how to control it, how to get people saved we want to be saved, how to control the work of the spirit of God in a person's life. But the truth is, we cannot. The best we can do is create a shallow and superficial form of religion that will not last in a man's life and cannot change a man's soul.
So what do we do? We wake up each morning trusting the Lord to do as He pleases in the hearts and souls of men.
We serve the Lord
We study His Word
We worship and glorify Christ
And we let the wind blow where it listeth.
