8The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”

The Holy Bible: English Standard Version. (2016). (Jn 3:8). Wheaton, IL: Crossway Bibles.

It is the devil’s scheme to elevate some people; then, as soon as they believe, they will be lured away from the faith and will seize upon matters not recorded in God’s Word. They will take issue with God and brood over the question why God does not bring the entire world to faith and salvation. They will speculate on the wondrous works of God, on His government of the world and on His judgments. But here is where we should be smart enough to rebuff the devil and say: “I will be content with the wind spoken of here, that is, with faith. If I am content with the sound of this wind, I shall fare well. Then I am safe, and I stand on solid ground. But I do not want to know what God has not revealed in His Word; that I will leave to the angels.”

Some things, on the other hand—for example, God’s way of judging and ruling the world—have not been revealed to me. Earthly knowledge is too little for me, and heavenly knowledge is too much. Nicodemus is concerned about worldly affairs, about this life, and about other things that are directly contrary to the Ten Commandments; Annas and Caiaphas were preoccupied with similar shams. Others want to be too smart and try to know too much. But we must walk straight ahead, swerving neither to the right nor to the left. We must remain on the royal way, following the sound of the Word and without prying into the wisdom of the angels. If I cling to what has been revealed to me by the sound of the wind—for I am not to discard everything on the left side—I cannot stray. As for the rest, whatever I am not intended to know I leave to God.
