Here are some Bible verses (KJV) [emphasis added] that validate the expression, "The Old Testament is Christ concealed, the New Testament is Christ revealed." As you study God's Word in light of this truth, I trust your heart too will burn as you discover and look ever more carefully at the abundant symbols relating to our Lord that fill the pages of the Old Testament. May you also come to the realization that Christ is on every page.

Matthew

13:34All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them: 13:35That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world.

Mark

15:37And Jesus cried with a loud voice, and gave up the ghost. 15:38And the veil of the temple was rent in twain from the top to the bottom.

Luke

8:9And his disciples asked him, saying, What might this parable be? 8:10And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.

24:25Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken: 24:26Ought not Christ to have suffered these things, and to enter into his glory? 24:27And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.

24:32And they said one to another, Did not our heart burn within us, while he talked with us by the way, and while he opened to us the scriptures?

Romans

5:12Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: 5:13(For until the law sin was in the world: but sin is not imputed when there is no law. 5:14Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come. 5:15But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. 5:16And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification. 5:17For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.) 5:18Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life. 5:19For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous. 5:20Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound: 5:21That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.

11:7What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded 11:8(According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day. 11:9And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them: 11:10Let their eyes be darkened, that they may not see, and bow down their back alway. 11:11I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.

I Corinthians

2:7But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory: 2:8Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory. 2:9But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. 2:10But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.

10:1Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea; 10:2And were all baptized unto Moses in the cloud and in the sea; 10:3And did all eat the same spiritual meat; 10:4And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.

10:11Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come.

15:51Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 15:52In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.

II Corinthians

3:12Seeing then that we have such hope, we use great plainness of speech: 3:13And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: 3:14But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ. 3:15But even unto this day, when Moses is read, the vail is upon their heart. 3:16Nevertheless when it shall turn to the Lord, the vail shall be taken away.

4:3But if our gospel be hid, it is hid to them that are lost: 4:4In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.

Galatians

4:21Tell me, ye that desire to be under the law, do ye not hear the law? 4:22For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. 4:23But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. 4:24Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. 4:25For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. 4:26But Jerusalem which is above is free, which is the mother of us all. 4:27For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband. 4:28Now we, brethren, as Isaac was, are the children of promise. 4:29But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. 4:30Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the free woman. 4:31So then, brethren, we are not children of the bondwoman, but of the free.

Colossians

2:16Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: 2:17Which are a shadow of things to come; but the body is of Christ.

Hebrews

9:8The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing: 9:9Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience; 9:10Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation. 9:11But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; 9:12Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.

9:24For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:

10:1For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
