Consider Nehemiah, as he stood before the king. (Neh. 2:4) Or Abraham's servant, as he went about his master's business. (Gen. 24:12-15) Hannah also stood before the Lord, her lips moving but her voice not heard. (I Sam. 1:13)
But I've recently realized I miss praying on my knees. On my knees makes the world go away. On my knees strengthens my focus. When my voice breaks the silence I find I strive harder to truly articulate the longings of my heart.
On my knees keeps me from getting above myself. My prayers are humble requests, not selfish demands. On my knees reminds me whom I serve; a God who is not only my Savior, but my King and my Lord. A God before whom I say "Who is Valerie, that thou art mindful of her?" On my knees I'm aware I serve a God who is to be feared, respected, and honored.
It is in times of trouble that I most desire to pray like Daniel, on my knees and turned toward his throne, giving thanks to the Lord and making supplications with all my heart.
O Come, let us worship and bow down: let us kneel before the Lord our maker. (Ps. 95:6)
