“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)

     Guy N. Woods once illustrated this verse in the following way: He told his audience that many of them would not be old enough to remember this but that he did –there was a time when automobile windshield wipers were operated manually.  That is, you operated a lever control-ling the single wiper blade as you drove.  Not that I ever doubted brother Woods’ words, but I had never seen such a thing until recently.  While visiting a museum I saw a 1928 Ford truck and noticed that it had a single wiper blade con-trolled by a handle inside the cab.
    As brother Woods, to finish the analogy, pointed out, nowadays we flip a switch and the work of wiping the windshield is done automatically.  Such is the benefit of the cleansing blood of Christ to the Christian.  It keeps on cleansing as we keep on walking in the light.  The word cleanses is a verb in the present tense and denotes continu-ous action.  The sense is if we continue to walk in the light of God’s truth, then the blood of Christ keeps on cleansing.
    Of course, it is meant that the blood of Christ cleanses us from all sin solely upon the conditions on which it’s power can be made available to man – living in the truth and by confession of past sins (Vs. 9).
