I do not believe in gray, either you are in the light or in the dark. There is nothing that is gray. If you are in the dark, there is no light. If you are in the light there is no darkness. How do you draw a boundary between the darkness and the light? Is it a fine line? Or a spectrum? Well for light there is the rainbow spectrum of Red, Orange, Yellow, Green, Indigo, Blue, and Violet. Yet each of these colors are all light.
There is also a matter of measuring the intensity of the light usually in watts. Does a 40 watt bulb light bring light into a room just like a 150 watt bulb? Once the light is on, is the room then light and no longer dark regardless of the intensity of light?
That is how I look at the room, light and dark do not coexist, you are either in a room that is in the light or in a room that is not in light, which is the dark.
As it relates to Theology, the study of God, which yields knowledge about God that should spur one toward wisdom, the application of that knowledge. Either the bible is in the light and teaches about God or in the dark and distorts God? It is either inerrant and infallible in all its content or it is not? Either the bible is true or it is not true? It can not be halfway true. Every half truth is a lie. So why trust any of it? Or which part do I trust?
The Liberty Christians have in Christ, is living in the light. There is no darkness in the liberty Christ gives. Christ liberates from sin and death, the expressions of darkness. So Christian Liberty is not living in gray areas and light areas. It is only living in the light.
If it is gray, that is darkness. My paraphrase of James 2:10 “If you break even one point of the law, you are guilty of all.” For me, the Bible is teaching that gray is a rational way to ignore a little darkness or sin, and gray is darkness and not light.
