“A Door Stood Open”
Throne Of Heaven:
According to the Bible, the man sitting on the throne looked like jasper and carnelian. There was a gorgeous rainbow with an emerald color.
Twenty-four thrones around God with twenty-four elders seated:
Surrounding the throne were 24 other smaller thrones. The elders seated on the thrones were dressed in white. The number 24 was for double the good. For example 12 disciples doubled is 24 and there was 12 tribes of Israel so doubled its 24.
The Seven spirits of God:
Wisdom, Understanding, Counsel, Knowledge, Fortitude, Piety, and Fear of the Lord with wonder and awe are the 7 gifts of the Lord.
