Eternal life is knowing God

"Jesus spoke these words, lifted up His eyes to heaven, and said:

'Father, the hour has come. Glorify Your Son, that Your Son also may glorify You, as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him. And this is eternal life, that they may know You, the only true God, and Jesus Christ  whom You have sent."  John 17:1-3

"He is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist. And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence."  Colossians 1:15-17

"Thus says the Lord: 'Let not the wise man glory in his wisdom,
Let not the mighty man glory in his might, nor let the rich man glory in his riches;
But let him who glories glory in this, that he understands and knows Me,
That I am the Lord, exercising loving-kindness, judgment, and righteousness in the earth. For in these I delight,' says the Lord." Jeremiah 9:23-24

"... finding fault with them, He says:  '...this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. None of them shall teach his neighbor, and none his brother, saying, ‘Know the Lord,’ for all shall know Me, from the least of them to the greatest of them. " Hebrews 8:8-11 [Quoting Jeremiah 31:31-34]

Only by His Spirit can we know Him

"...as it is written:

       'Eye has not seen, nor ear heard,
       Nor have entered into the heart of man
       The things which God has prepared for those who love Him.'
But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the  spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God....
     "But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned. But he who is spiritual judges all things, yet he himself is rightly judged by no one. For 'who has known the mind of the Lord that he may instruct Him?' But we have the mind of Christ."  1 Corinthians 2:9-16

 

"Oh, the depth of the riches both of the wisdom and knowledge of God!

How unsearchable are His judgments and His ways past finding out!
For who has known the mind of the Lord? Or who has become His counselor? Or who has first given to Him and it shall be repaid to him? For of Him and through Him and to Him are all things, to whom be glory forever. Amen."  Romans 11:33-36

He opens our "eyes" to see the truth

"...as He sat at the table with them, that He took bread, blessed and broke it, and gave it to them. Then their eyes were opened and they knew Him; and He vanished from their sight. And they said to one another, 'Did not our heart burn within us while He talked with us on the road, and while He opened the Scriptures to us?'" Luke 24:30-32

"And He opened their understanding, that they might comprehend the Scriptures." Luke 24:45

"The Lord opened her heart to heed the things spoken by Paul. And when she and her household were baptized, she begged us, saying, 'If you have judged me to be faithful to the Lord, come to my house and stay." Acts 16:14

Many think they know Him but never received Him

"I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. And in them the prophecy of Isaiah is fulfilled, which says: 'Hearing you will hear and shall not understand, and seeing you will see and not perceive; For the hearts of this people have grown dull....
      "But blessed are your eyes for they see, and your ears for they hear; or assuredly, I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it."  Matthew 13:13-17

"But to the wicked God says: 'What right have you to declare My statutes, or take My covenant in your mouth, seeing you hate instruction and cast My words behind you? ... You thought that I was altogether like you; but I will rebuke you...." Psalm 50:16-17, 21

"'For My thoughts are not your thoughts, nor are your ways My ways,' says 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.'" Isaiah 55:8-9

"For the Lord does not see as man sees; for man looks at the outward appearance, but the Lord looks at the heart." 1 Samuel 16:7

"You thought that I was altogether like you; But I will rebuke you..." Psalm 50:21

"[Jesus] was the true Light which gives light to every man coming into the world.  He was in the world, and the world was made through Him, and the world did not know Him. He came to His own, and His own did not receive Him. But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God." John 1:9-13

"And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth." John 1:13

"...do you despise the riches of His goodness, forbearance, and longsuffering, not knowing that the goodness of God leads you to repentance? But in accordance with your hardness and your impenitent heart you are treasuring up for yourself wrath in the day of wrath and revelation of the righteous judgment of God."  Roman 2:4-5

"Has not God made foolish the wisdom of this world? For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe. For Jews request a sign, and Greeks seek after wisdom; but we preach Christ crucified, to the Jews a stumbling block and to the Greeks  foolishness, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. Because the foolishness of God is wiser than men, and the weakness of God is stronger than men." 1 Corinthians 1:20-25

"....we speak the wisdom of God in a mystery, the hidden wisdom which God ordained before the ages for our glory, which none of the rulers of this age knew; for had they known, they would not have crucified the Lord of glory." 1 Corinthians 2:7-8

Attributing His works to human intellect or other gods

"...the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools.... Therefore God also gave them up to uncleanness, in the lusts of their hearts, to dishonor their bodies among themselves, who exchanged the truth of God for the lie, and worshiped and served the creature rather than the Creator...." Romans 1:18-25

"...you should turn from these useless things to the living God, who made the heaven, the earth, the sea, and all things that are in them, who in bygone generations allowed all nations to walk in their own ways. Nevertheless He did not leave Himself without witness, in that He did good, gave us rain from heaven and fruitful seasons..." Acts 14:15-17

Those who know Him will tell others

"You have done all these great things, to make Your servant know them. Therefore You are great, O Lord God. For there is none like You, nor is there any God besides You...."  2 Samuel 7:21-22

"[Jesus] is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist. And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence." Col 1:15-18

"In God we boast all day long, and praise Your name forever." Psalm 44:8

"...not many wise according to the flesh, not many mighty, not many noble, are called. But God has chosen the foolish things of the world to put to shame the wise, and God has chosen the weak things of the world to put to shame the things which are mighty; and the base things of the world and the things which are despised God has chosen, and the things which are not, to bring to nothing the things that are, that no flesh should glory in His presence. But of Him you are in Christ Jesus, who became for us wisdom from God -- and righteousness and sanctification and redemption -- that, as it is written, 'He who glories, let him glory in the Lord." 1 Corinthians 1:26-31

"...now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known." 1 Corinthians 13:12

"Now to the King eternal, immortal, invisible, to God who alone is wise, be honor and glory forever and ever. Amen." 1 Timothy 1:17
