An Exposition of Hebrews 3:7-12, by A.W. Pink.

Wherefore (as the Holy Ghost saith, To day if ye will hear his voice, Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: When your fathers tempted me, proved me, and saw my works forty years. Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways. So I sware in my wrath, They shall not enter into my rest.) Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.
~ Hebrews 3:7-12

Known unto God are all his works from the beginning of the world. And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
~ Acts 15:18, Revelation 13:8

For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it. For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world. For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.
~ Hebrews 4:2-4

For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, And have tasted the good word of God, and the powers of the world to come, If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
~ Hebrews 6:4-6

And the LORD said, I have pardoned according to thy word: But as truly as I live, all the earth shall be filled with the glory of the LORD. Because all those men which have seen my glory, and my miracles, which I did in Egypt and in the wilderness, and have tempted me now these ten times, and have not hearkened to my voice; Surely they shall not see the land which I sware unto their fathers, neither shall any of them that provoked me see it:
~ Numbers 14:20-23

I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin. God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel, saying, Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life. But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal. Even so then at this present time also there is a remnant according to the election of grace.
~ Romans 11:1-5

Your father Abraham rejoiced to see my day: and he saw it, and was glad.
~ John 8:56

And till Moses had done speaking with them, he put a vail on his face. What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded. But if our gospel be hid, it is hid to them that are lost:
~ Exodus 34:33, Romans 11:7, 2 Corinthians 4:3

And when he was alone, they that were about him with the twelve asked of him the parable. And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables: That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them.
~ Mark 4:10-12

He that despised Moses' law died without mercy under two or three witnesses: Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
~ Hebrews 10:28, Romans 9:18

Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
~ Romans 9:6-8

There remaineth therefore a rest to the people of God.
~ Hebrews 4:9

And he shall set the sheep on his right hand, but the goats on the left.Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
~ Matthew 25:33-34

A further aggravation of Israel's sin is that they saw God's wondrous works for "forty years." God continued His wonders all that time: despite their unbelief and murmuring the manna was sent daily till the Jordan was crossed! Man's incredulity cannot hinder the workings of God's power: "What if some did not believe? shall their unbelief make the faith of God without effect? God forbid" (Romans 3:3).
