V.1-6 A seraphim is a heavenly being, possibly like an angel. They are concerned about the Lord’s glory. Notice what they say.
V.5-7 When Isaiah hears what the seraphim say about the Lord, he realizes that he is in the Lord’s presence. This causes him to know how unclean he is himself. This is always the result when we are brought close to the Lord. We see how careless we have been. But when we confess to the Lord the things we have been going on with which we realize are not pleasing to Him, then He restores us.
V.8 Now Isaiah is ready to be used by the Lord. We cannot be suitable for the Lord to use unless we have had Isaiah’s experience.
V.9-13 Israel was so disobedient, that God has to tell Isaiah to go and tell them that He was going to blind them so that they would not be able to understand God. Blindness is happening today in our lands. People are not obeying God’s Word, so 2 Corinthians 4:4 is becoming true. We all need to be very careful to live out everything we have learned from the Bible. If we don’t we will not see clearly.
