"For I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day" (2 Timothy 1:12)
In religion more than in any other field of human experience a sharp distinction must always be made between knowing about and knowing. The distinction is the same as between knowing about food and actually eating it. A man can remain spiritually dead while knowing all the historic facts of Christianity.
"This is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent" (John 17:3). We have but to introduce one extra word into this verse to see how vast is the difference between knowing about and knowing. "This is life eternal, that they might know "about" thee the only true God, and Jesus Christ, whom thou hast sent."
That one word makes all the difference between life and death.
We dare not conclude that because we learn about the Spirit we for that reason actually know Him. Knowing Him comes only by a personal encounter with the Holy Spirit Himself.
The Spirit is an imperative necessity. Only the Eternal Spirit can do eternal deeds.
