Isaiah 6:1-2 NIV
"In the year that King Uzziah died, I saw the Lord,"
King Uzziah is a symbol for pride. When pride died, Isaiah was able to see the Lord. He has been a prophet yet he did not see the Lord before. He prophesied five chapters until now. From here is a different story. We may be prophets or so called servants of God. Yet it takes humbleness and lack of pride to see the Lord.
"...train of his robe filled the temple."
We usually think that the Lord is in his temple. Now the temple is in his train. Any big temple cannot contain God the Father. He humbles himself to meet us and fit in our humble rooms because he is in love with his people.
"...With two wings they covered their faces, with two they covered their feet,"
The word "they covered" sounds that they are exposed to something that they could not bear. They have been there for decades yet they are not accustomed to the power of his presence. Some worship-leaders are casual because it has been usual to them. These angels are telling us that the Lord is new to them in every fraction of a second. This experience is really awesome, glorious. Wow! What a wonderful God I have!
Love you Lord!!
Daniel prayed at his house. Gabriel came and helped him. When he prayed he did not took care of ceremonial cleaning or bathing anything like that (Dan.10:3). David also prayed at his house, prayed seven days for his child.
