The room seems a bit dark.  Would you mind if I turn on a light?  John tells us a very simple but important truth regarding who God is. He writes, This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all (1 John 1:5).
God is light.  The truth of this ought to affect the way that we think about God.  The concept of “light” is all about the purity, holiness, and rightness of God.  God doesn’t do things with hidden evil motives.  God is not sitting up in heaven thinking up ways to make you miserable so He can laugh at you and watch you suffer.  This is not what God is all about.  We may indeed go through difficult times as God’s children, but it’s not because of dark scheming.  God’s plans for His children are for the good.

The truth John shares also affects the way we see ourselves.  If we claim to have a relationship with God, but our lives are filled with disobedience and darkness, something isn’t right.  Our relationship with God ought to be moving us out of our old dark, evil ways, and closer to God.  In fact John says that if you claim to know God but live a life of darkness, you’re lying (1Jn. 1:6) and you don’t know God like you claim.  “But wait”, you say.  “I am a Christian but I still have some “dark” things in my life.  What do I do about those things?”  John goes on to say, “But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin” (1 John 1:7).  Turn on the light.  Make the right choices.  You’ll find others to help you.  You’ll find cleansing.  Just turn on the light.
