2 Corinthians 6:14
14
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
Heaven and Hell #139
139. It should be realized that the divine good and divine truth that come from the Lord as the sun in the heavens are not in the Lord but are from him. All that is in the Lord is divine love, which is the reality from which divine good and truth become manifest. Becoming manifest from reality is what "emanating" means. This too can be illustrated by comparison with our world's sun. The warmth and light in our world are not in the sun but are from it. In the sun there is nothing but fire, and warmth and light become manifest and emanate from it.
