If Moses doesn't make it into the "promised land" by his mostly wonderful life, what hope do we have? The answer is NONE. That is, in and of ourselves, by our list of supposed "merits" and credits in some celestial ledger, NONE. We have no chance of achieving heaven by our merits alone.
And that is the point. We are going to need some heaven-sent help. We are going to need the perfect one, the unblemished one, the truly righteous one. How do we know we need Jesus? Because even Moses didn't make it by his ledger-book-of-goodness.
