If you look closely at the lens of a Single Lens Reflex (SLR) camera, you’ll see a ring near the base of lens that controls the F-Stop. The F-Stop represents the size of the aperture, or opening, in the lens. The lower the number, the more light is allowed to enter the camera to create a bright and vivid image. The higher the F-Stop, the slower the shutter needs to be to get enough light for a full exposure. If the shutter is too slow the image will be blurry.
Our hearts can act like an F-Stop to God’s light. If you open it wide, you will be bathed in God’s goodness and can absorb more love and knowledge and grow as a Christian. But if you close your heart, you open yourself to blurry images of God, leaving yourself vulnerable to underexposure, leading to Satan’s darkness.
James 4:8 – “Draw near to God, and he will draw near to you.”
1 John 1:5 – “This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.”
