All These Things

Isaiah 45:7 (ESV Strong's)

I form light and create darkness,

I make well-being and create calamity,

I am the LORD, who does all these things.

The light has always existed because the Lord is light. Darkness is a characteristic of creation, apart from God. Calamity did not exist before the creation of heaven and earth. 

Why would the Lord do this? To create the body of Christ through a new creation in the image of our Lord, fashioned out of our flesh and the light of the Lord. Our flesh is made one with the Trinity of the one God, entering His eternal life and fellowship. 

We put on the righteousness of Christ and He takes the flesh of man to join heaven and earth before His work is done and His word fulfilled.
