Which of the Praying Postures to Use?

Which one of the praying postures is the proper posture to adopt when praying? Walter Veith explains how different circumstances require different attitudes. Is it necessary to kneel at every prayer, or can we stand? Consider that our posture depends on the formality of the situation. However, note that there are public prayers and private ones. How we approach God on a one-on-one conversational basis is different than public prayer. Veith explores different prayer settings and some suggestions for posture.
