What makes a prophet a prophet? He's the guy who's not satisfied with the answers he gets from the people of his times so he takes it to the top: he goes directly to God.
God intends to bring about a permanent physical separation of light from darkness. Light weight and light bearing are synonyms, like dark and heavy are. In general heavier, denser materials are darker.
Light and darkness have to be separated because the manifestation of free will is only possible by combining them.
To divide, disperse, divide, be out of joint, part, scatter abroad, separate self, sever self, stretch.
Separation is a scriptural doctrine which is generally thought of in terms of Christians holding themselves apart from the rest of the world and avoiding worldly distraction which can lead us into sin. There's more to it than that.
The purpose of creation is to separate good from evil. A reasonable question is: Why were they mingled together in the first place? If God is good, then the evil had to be created from good. The sinless became sin.
If you want to deny God, then God isn't going to stop you. In fact, if you want to reject the truth then the Bible tells us how you will end up: with a mind which cannot comprehend the truth.
One of the things which allows Matty's Paradigm to be a consistent with the broad narrative of scripture is understanding that creation has a specific purpose. This purpose harmonizes physics with spirituality.
On the 7th day God rested from his work of creating. This may have been the last time that the world could have been described as very good. It was the peace before the storm. Tomorrow we begin to look at what happens next.
This level of understanding takes Christianity from, supposedly, being the realm of the ignorant, uneducated science denier to be on a par with the intellectual complexity of relativity and subatomic physics.
