Q. What should be our posture in prayer?
A. We are to pray in all postures but especially on our knees.
The Bible repeatedly calls us to bow down before God. We are in the throne room of the Worthy King of the Universe (Eph 3:14). We also sit and stand before Him, raise holy hands, prostrate ourselves, and pray on our beds. All of these postures and more are appropriate at various times when they are done in faith.
