John 9:4-5 - “As long as it is day we must do the work of Him who sent me. Night is coming, when no one can work. While I am in the world, I am the light of the world.”
Jesus was speaking of His time on earth when He spoke these lines. “As long as it is day,” He said, referring to the time He had before He was crucified, “we must do the work of Him who sent me.” There was so much that needed to be done. Everywhere Jesus looked there were people that were lost and hurting. Some in pain and physical ailment and others downcast and defeated. As long as He was on earth He was the Light in their darkness.
Jesus knew a time was coming when He would be leaving and would not be there to help them anymore, so He didn't want to waste the time He had. Now that He is not here anymore in the natural He has given us the task of continuing His work. While on earth He showed us how we are to live and what we are to do. He is our example.
Therefore, we must apply this verse in our own lives. While we are here on earth and are healthy and capable, we need to do the work of God. We must be the ones to minister to those who are lost and hurting. There will be a day when we will no longer be able to carry on the work of God, but until then we must never tire of doing what is right. Now we are the light of the world through Jesus. Let your light shine to those around you.
