So Jesus said to them, “The light is among you for a little while longer. Walk while you have the light, lest darkness overtake you. The one who walks in the darkness does not know where he is going. While you have the light, believe in the light, that you may become sons of light.”
I can't say that I have much to teach on this right now, only some observations; the biggest one being that Jesus confirms here, near the end of his time on earth, that he is the light spoken of in the beginning of this book. He lets us know that walking in his light will keep us from being overwhelmed by darkness. He goes on to say that believing in the light allows us to become sons (children for those who prefer gender neutral) of light.
With Jesus being as multi-faceted as God the Father, we find many descriptions of him in the Bible. Son of God is probably the most recognizable followed by the Word of God and Lamb of God. Each of these helps us to understand an aspect of who and what Jesus is. Now we see him as the Light of God.
Jesus reveals God to the world. He pushes back the darkness of this world with his Father's goodness. The path he lights for us is an alternative to what we see in the world around us; in fact, Jesus says that we don't even know where we are going in the darkness. We are lost; each of us merely stumbling in the dark without a light to show the way. As we stumble we will grasp onto anything that seems to give guidance or purpose to our lives without realizing that anything in this world we grab is a temporary thing. Nothing in this world lasts forever, and when that thing that we follow goes away or shows itself to be lacking in substance we just wander aimlessly until we find something else to grab onto.
But Jesus offers us a light to guide our way through this world. He is the light of the one who is always and always is. God is permanent. God is forever.
Life seems very dark for many right now. Fear, anger, and isolation are a bad combination; and these are common feelings around the world today. But they, like all worldly things, are temporary and fleeting while God is forever and solid. Grasping onto him will give us the strength to come through the current situation stronger than how we entered it. His light will show us a way to be less fearful and frustrated each day and help us to know that isolation from other humans does not make us alone. It allows us to find out what is truly important to us.
Be strong in the Lord.
