Amazingly, many who practice contemplative prayer cite Psalm 62:5 in support of the practice: "For God alone, O my soul, waits in silence, for my hope is from him." However, this verse has nothing to do with prayer or contemplation but rather simply encourages believers to wait without distraction in eager expectation for God to act in deliverance.
Another verse taken out of context is Psalm 46:10 (KJV): "Be still, and know that I am God." The act of being still, however, has nothing to do with prayer or contemplation, but simply indicates that one should slow down and trust God rather than get in a fuss over tough circumstances.
