We are not told to kneel or stand or lie on the floor when we pray. Prayer is, in its simplest sense, a request. The better we know ourselves, the more we will know that we are incredibly needy people. Of ourselves, we can do nothing. If we want to accomplish anything worthwhile, we must seek God's help.
Prayer is a cry for help.
And since our needs never end, our prayers should never cease. Rely on God Self-reliance is sin. It is arrogant for us tiny creatures to think that we can do whatever we want, that we can control our own destinies, that we can decide for ourselves what is right and what is wrong. The truth is that humans do not have the wisdom or the power. He is upholding us even as we ignore him.
