Luke 11: 33-36 "No one lights a lamp and then hides it or puts it under a basket. Instead, it is put on a lamp stand to give light to all who enter the room. Your eye is a lamp for your body. A pure eye lets sunshine into your soul. But an evil eye shuts out the light and plunges you into darkness. Make sure that the light you think you have is not really darkness. If you are filled with light, with no dark corners, then your whole life will be radiant, as though a floodlight is shining on you."
A couple of things jump out at me from this text. The eye is the gateway to the soul. What we choose to gaze upon determines the condition of our souls. It does matter what we gaze upon. It does affect us whether we think it does or not. Imagery is captured in the brain and often comes back to haunt us later on. It is important that we protect our eyes from what we watch and read.
We have to be careful about the quality of light we use to guide us. We determine how pure our light is. If we allow sin to hang around it will dim our light. Sin is sin and any sin will affect the quality of light within us. The less sin we harbor, the more radiant our light will be. The more we radiate the Light, the more light we will shed on our world. The more Light we have, the more we will enjoy dwelling in the Light.
A dim light may get us where we are going, but it won't keep us from seeing the pitfalls along the way. We can easily stumble and fall and even lose our way sometimes. Protect your soul and stay connected to the Light without any obstructions so that your light may shine brightly and be a floodlight on all around you.
One other thing, make sure the light you think you have is not really darkness. Sin is deceptive and often masquerades itself as light. Get into and stay into the Word of God so that you will be guided by Truth and not lies. The Holy Spirit will never lead you astray if you keep your eyes focused on Christ, who is our light, and stay in the Word which speaks to us of Christ and His way.
Let Christ shine in your heart and let Him have access to every part of it. Do not try to hide anything from Him. The more you let Him shine in you, the more you will radiant Him through your life.
