Help...because this kind ties in with predestined....The Book of Life has already been written. How can that be possible unless He foreknew....
My answer is that He knew all things from beginning to end and nothing is hid from Him.
But to say He already chose for us who would be saved is incorrect. It is just to say that when He saw everything up until the end He saw those who would choose to believe in Him and be saved.
So...it is such a complex subject and needs alot of studying.
If the book of life is the naming of all who would live, and that names are blotted from the book when they sin, this would agree with everything said in the Bible about this book, so far as I can see.
Much love!
