Darkness privately interprets the light. When darkness privately interprets the light then it makes that light darkness. If my eye is not single, then I will never be full of light. If I know good and bad then that will privately interpret love. Love is the Tree of Life. I am required to eat at only one tree and no other. I must have love, or else my light is not light, it is darkness.
The answer to life is that the true light now shines. "He that loveth his brother abideth in the light, and there is none occasion of stumbling in him" (1 John 2:10). If we can love our brother with a love that cannot fail then, without question, our rationalizations and knowledge of sin and weaknesses can never dominate our light. For love has eliminated these. Now, there is none occasion of stumbling.
Among the brethren, there is one way of proving all things, and that is through a love that is full of light. In Proverbs 30:19, "The way of an eagle in the air." What a wonder this is. Why? The law of gravitation is still existing, but the eagle has a capacity to fly despite this law. How true it is! We still have the law of sin and death. We still have a nature that is subject to darkness and the strength of our emotions without God. Yet, the law of the Spirit of life in Christ Jesus has made us free from the law of sin and death. Love goes beyond knowledge, peace beyond understanding, and Christ carries us beyond our limitations of how we limit God.
