When I think of what Q means when he said dark to light I think of these verses.
Love you Q love you POTUS (no homo.
“This is the verdict: Light has come into the world, but people 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 their deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.”
John 3:19-21 NIV
