What comes into your mind when you think about God is the most important thing about you.  (A.W.Tozer).  What do you think when you think about God?  It has been said we can have knowledge about God, that is we can know about God, but we can never have complete (exhaustive) knowledge about God.  Why is that?  It is because God is an infinite and incomprehensible mystery.  Is God an infinite and incomprehensible mystery to you? 

Now, if this infinitely incomprehensible God did not choose to reveal Himself, we would know nothing about Him.  But He did choose to reveal Himself to us in a limited way. I must emphasize, God revealed Himself in only one place, and that is the Bible that contains 66 books.  We are finite beings and can only come to know God based on His limited revelations of Himself to us.  We who are finite can never come to know the infinite God in the fullness of His being, not now, not ever. Why is that?  To know God in the fullness of His being, you will have to be God. 

God has revealed that He is omniscient.  Can you really comprehend what that means?  Do you or can you know the full extent of all that God knows?  Do you or can you know the full extent of God’s wisdom?  If God were to say to you like He said to Job,  “Now gird up your loins like a man, And I will ask, and you instruct Me!”, how would you respond to God?  (Job 38:3).

Consider the following verses :

Deut.29:29, “The secret things belong to the Lord our God, but the things revealed belong to us and to our sons forever, that we may observe all the words of this law.”  For example, in  Acts 1:7  Jesus’ answer to the disciples’ question was, ““It is not for you to know times or epochs which the Father has fixed by His own authority.”

Isa.55:8-9, “For My thoughts are not your thoughts,
Nor are your ways My ways,” declares the Lord.
“For as the heavens are higher than the earth,
So are My ways higher than your ways
And My thoughts than your thoughts.

Isa.40:28, “His understanding is inscrutable.”

Psa.145:3,  “His greatness is unsearchable.”

Job 9:10,  “Who does thing, unfathomable.”

Psa.147:5, “His understanding is infinite.”

1Cor.2:11-12,   “For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God. ¹² Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God,” 

Rom.11:33, “Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and unfathomable His ways!” 

Now here is the key issue  :  finite men want to draw back the curtains and remove the mystery from God.  They want to know and understand everything about God. But the problem is two-fold  : (1). Remove the mystery from God (if you are able) and God will cease to be God.  (2). To know everything about God is to become Divine. And we are back to Satan’s diabolical promise to Eve, “You will be like God….”  (Gen.3:5). Ever since the fall, fallen men have not given up on their evil quest to become like God.  Fallen men have not given up on their evil quest because they continue to believe Satan’s diabolical lie and their hearts continue to be idolatrous. (cf. Rom.1:20-23). 

If you cannot humbly bow with a repentant heart to the truth of God’s infinitely mysterious and incomprehensible nature, you are an arrogant Satanic idolater of the highest order.  (cf. Job 42:1-6).  In the words of Jesus, “You are of your father, the devil.”  (Jn.8:44). 

Have you ever heard someone say as they read / study the Bible  :  I cannot understand this.  This does not make sense to me.  This is not logical.  How can you expect me to believe this when I do not understand it?  Duh!!  What do you expect when you are dealing with an infinite God whose knowledge, wisdom, and understanding are infinite, inscrutable, unfathomable, etc., etc.?  But let me ask  :  is your problem understanding what God has revealed?  Or is your problem your refusal to believe by faith what God has revealed and / or to obey God? Is your problem intellectual or moral?

Let me illustrate. Jn.3:36 says,  “He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him.”  To believe is to believe by faith the gospel God the Father has revealed about His Son.  The result is eternal life (salvation) in His Son.  Now note the words  “does not obey”.  This is the translation of one Greek word, apeitho, and it describes disobedience that is rooted in unbelief.  In this context it does not describe the inability to understand.  It describes the refusal to believe by faith the gospel God the Father has revealed about His Son. In other words, the problem is not one of understanding (intellectual). The problem is in the profession that makes the false claim, “I do not understand”, and in the act of the will that refuses to believe by faith what God has revealed.  In other words, the problem is moral.  The sinner will not be cast into the lake of fire because he does not understand the gospel.  The sinner will be cast into the lake of fire for all eternity because he refuses to believe the gospel of the Lord Jesus Christ.

Heb.11:6,  “And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him.”
