Seraphim

Tonight, as I was driving home from the airport, I was listening to Pastor David Jeremiah on the radio. I hadn't heard him before. He was speaking about angels - specifically about the Seraphim, described in Isaiah 6.
Isaiah writes,
In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple. 2 Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. 3 And they were calling to one another:
“Holy, holy, holy is the LORD Almighty;
the whole earth is full of his glory.”
The pastor described the wings of the Seraphim and explained that four of their six wings were used for worship - to cover their faces and feet in worship of the Lord. And two of their wings were for work - for flying. He observed that we ought to follow their lead and use 2/3rds of our energy for worship and only 1/3 for work - he remarked that we often have this backward and that leads to all kinds of trouble.
Hmmmmmm.....that's convicting!
