We try to use logic with many things ...and logic can be useful. But, it can be logically wrong too.
I believe the Bible is logically right. In the beginning was the paradise of the Garden of Eden. A desire for something more, when aspired to unwisely, most often gives us so much less ...giving up on what could have been so much more.
There was the Law. Then comes the GIC ...Guaranteed Investment Contract. We invest very little, and God invested the life of His Son. Eternal life is guaranteed. This is what God promises. Our name entered into the Book of Life ...eternal paradise, what more could we want?
