Searching for something that is dark in the heavens almost seems counterintuitive. Things in the light are typically easier to see than things in shadow. So what happens when what you want to see is black rather than light?
In many objects the dark parts provide contrast and depth to what is being observed. Stellar clouds, which are extremely thin and large by measurement standards, show up very dark because they block stellar light. It’s as if your hand was in front of a dim light in front of you. Your hand is in shadow; the dim light is blocked. Put that in stellar distance terms in a galaxy or nebula, and dark lanes or black areas begin to make sense.
The Snake Nebula is a good example. Make sure your screen is at the right angle to your eyes, but you should be able to see a winding black area from left to right. Our Mighty Creator God made us (our eyes and mind) sensitive to contrast. Typically we look for light things, but when you look at this observing sheet, look for the “absence of light” and stars. So, you are seeing this immense but thin stellar cloud, but it is in front of a dense star field.
To God, what is dark is as easily seen as that which is in the light. That extends to lives as well as things. Nothing is hidden from His sight. In a very limited way, you get to experiment with this idea on this object, because you aim to see the reverse of what you normally might easily see. My rendering is not that good, but you get the idea when you examine it.
Extend this idea to yourself. A person might hide somethings or keep them in the dark. God can render them perfectly if He were to describe them to you or show you them in an instant. Hidden motivations, desires, and actions are perfectly understood. If He saw your life like this nebula, He would see beyond it–to include the immense and dense star field behind the cloud. He also sees it from all angles, knows its features inside and out, knows we observe it, and the list could go on.
Is that frightening? If repentance and his forgiveness have come to play as one comes calls out to Him, the answer is “no.” Consider plain spoken verses in John 3:19-21 that say, “This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God.
