Dane Ortlund has some great insight into the Christ Centered foundation of the Bible:
Jesus is not only the most important figure in the Bible, he is the key that unlocks it all, the light that illumines it all, the organizing principle, the climax prepared for and then presented. Jesus is the point of the whole Bible.
Remove Jesus from Bible, and you don’t have a hero hall of fame with one of the portraits
missing; you have a dark room without the light turned on.
C. S. Lewis famously said,
I believe in Christianity as I believe the sun has risen, not only because I see it, but because by it I see everything else.
The same point Lewis makes about Christianity and the world could be made about Christ and the Bible. Calvin helpfully said in the Institutes that the OT is the shadows, the NT is the substance. The whole OT is preparation for Jesus; the whole NT is proclamation of Jesus.
