Jesus wasn't plan B. Why do I say that? Well I've been thinking about that statement for a while. Chewing on it, mulling it over, spitting it out, and eventually picking it up and running with it. This statement if true, has profound consequences. If Jesus earthly life and death wasn't a hastily thought up idea after Adam and Eve sinned, then it means that God knew we would sin, and allowed sin to enter this world...and that thought, when you first think it, is like taking a whisk to your brain...at least it was for me. But enough theory, let's put Bible under that.
...and all who dwell on earth will worship [the beast], everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain. Rev 13:8
This verse splits humanity in two. Those who worship the beast, and those who don't. And those who don't had (past tense) their names written before the foundation of the world. So before the world was founded there was a book that had the names of believers written in it. And the name of the book was "the book of life of the lamb that was slain". So before the world was created there was a book belonging to the slain lamb. Before the world began, BEFORE sin came into this world, there was a plan that involved the lamb being slain for the redemption of sinners.
This is so integral to the plan of God that in heaven, of all the bazillion things they could sing about, they sing about slaughter....take that in. They sing of slaughter. (Rev 5:9 ish)
Jesus wasn't plan B. And that might mess with your head. But it also means that God is in control. So when this world seems out of control, it's not.
King Jesus reigns.
