Amen. As an all-too-typical unschooled Christian, I never spent much time reading the Old Testament.
Thanks to many of these fine threads, I've returned to the Old Testament and found Jesus Christ on nearly every page. It's truly amazing how Christ was foreshadowed in the Old Testament.
Not surprising, I suppose, since God wrote both Testaments from before the foundation of the world, all with the cross as its center.
For it is written, Then he said to them, These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.Luke 24:44 [my emphasis]
It's all about Him.
I remember a popular seminary question in Old Testament Survey, given as a test after each book of the Old Testament was surveyed, was to either write an essay on the particular book or trace the crimson thread of redemption through the same book of the Old Testament. After each book, varying degrees of book related questions were provided, but the same crimson thread of redemption option was available on each book review.
