Prophecy in Isaiah says "In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up..." We don't know what Isaiah did, but he was involved with the church. The church can be a calm and quiet place. But when God shows up things change. Isaiah saw God, he was scared and fell on his knees. An Angel came and put a hot coal to his lips and said his sins were forgiven. From 640BC to 580BC Isaiah spoke Gods truth. In a prophecy to Ahaz the Lord said through Isaiah "Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel."
