The spirit of man is the breath that the Lord breathed into man that gave him life. You could even call it our conscience. The candlestick was in the church shining to remove the shadows. The Light of Jesus shines within all believers and destroys darkness. It searches out all the hidden sins and brings them to light.
We are told by Jesus in Matthew:
Matthew 5:16 “Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven”.
God’s Light shining within us separates us from the darkness of the world. The light that is within us is the Light of Jesus.
