Muslims believe that Isaiah could not have seen God, as it is stated in the Quran that no one can see God and live.

The New Testament scholar consensus suggests that John 12:41 interprets Isaiah's vision in Isaiah 6 as a sighting of the prehuman Christ. This is significant because it implies that the glory Isaiah witnessed is indeed that of Jesus, who is identified as Jehovah. The argument is strengthened by the understanding that the name 'Jehovah' is uniquely attributed to God, and John’s application of this name to Jesus indicates His divine nature. Furthermore, the reverence for the name Jehovah among Jews underscores the importance of this identification, as it was not used lightly or applied to any creature. Therefore, the conclusion drawn is that John viewed Jesus as equal to the Father, which aligns with the Christian doctrine of the Trinity.
