Ecclesiastes 11:5 As thou knowest not what is the way of the spirit, nor how the bones do grow in the womb of her that is with child: even so thou knowest not the works of God who maketh all.

But I do know the way of the spirit!

This statement was true enough when Solomon wrote them before Christ. Every encounter that man had with God in the form of the Holy Spirit was external and mysterious.

John 3:8 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.

We are that great mystery to everyone who is not born of the spirit. But we who are born of the spirit, walk in the spirit, we know the way of the spirit. The spirit is no longer a mystery to us.

Ephesians 3:3, 17a, 19b How that by revelation he made known unto me the mystery; That Christ may dwell in your hearts by faith; that ye might be filled with all the fulness of God.

It was not possible in Solomon’s time for God to dwell in man. So holy and pure is God that no mortal man could live in the presence of God. But Christ, by His obedience, His death and resurrection made it possible for God to dwell in man by faith. He changed that.

John 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.

We become the great mystery to those who do not believe because like Solomon so many years ago, they cannot see the indwelling spirit and know His ways.

You must be born again of the spirit to know Him who is spirit.
