The holiness of God compels his people t respond with praise and worship. When we enter his presence through prayer, worship, and praise, it causes an irrepressible urge to acknowledge who He is to us. I believe this is also the situation that the entire angelic host find themselves in. Sometimes it can not be expressed in spoken words or singing voices. Sometimes these crude ways of communication will not suffice.
Sometimes in the pulpit i give up trying to convey what is in my heart, but i suspect there are those who hear the unspoken words of praise and worship tat defy expressin. May his name always be praised.
(There is none holy as the Lord, for there is none beside Thee, neither is there any rock like our God.) - 1 Samuel 2:2
