I am glad we can agree on this fact.
I believe Jesus Christ was the Lamb of God covenantally considered "slain" before the foundation of the world. (Rev. 13:8)
Nang
Matthew 13:35 (New King James Version)
that it might be fulfilled which was spoken by the prophet, saying:
“ I will open My mouth in parables;
I will utter things kept secret from the
foundation of the world."
Footnotes: Matthew 13:35 Psalm 78:2
Psalm 78:2-4 (New King James Version)
2 I will open my mouth in a parable;
I will utter dark sayings of old,
3 Which we have heard and known,
And our fathers have told us.
4 We will not hide them from their children,
Telling to the generation to come the praises of the LORD,
And His strength and His wonderful works that He has done.
Question: How is it that "things kept secret from the foundation/beginning of the world according to Matthew, are things that "we have heard and known" according to the Psalms?
Whatever is kept secret or hidden from the "foundation of the world" would not have been known to anybody until Christ revealed it. But if these things have been hidden since the time of King David then the Greek phrase "ἀπὸ καταβολῆς κόσμου", found in Matthew 13:35, should not be rendered "from the foundation of the world" but "because of the spiritual disintegration (sin and rebellion) of the world"--καταβολῆς means to throw down, destroy, or disintegrate not to build up.
Revelation 13:8 "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."
Again the phrase "ἀπὸ καταβολῆς κόσμου" is used and it makes more sense to render it "the Lamb slain because of the spiritual disintegration (sin and rebellion) of the world".
To say that Christ was slain before the world began makes no sense. To say that Christ was slain because of sin and rebellion makes perfect sense.
