..........congressmen in Virginia at a ball practice chose a pray stance as they prayed for wounded colleagues and Capitol police after a lone gunman shot at the participants early in the day.
A standing position with heads bowed.
I know because I saw it on my TV as the news was broadcast. People coming together to pray for others.
In biblical accounts of prayer many positions are noted: "Abraham fell on his face before God;" (Genesis 17:3) "Moses prayed with outstretched arms;" (Exodus 9:29) "King Solomon knelt before the altar with hands outstretched toward heaven;" (1 Kings 8:54) and Jesus prayed looking up to heaven." (John 17:1)
My 6 old attendees know that prayer is "talking to God," and there is not a required position.
Prayer's the expression of the attitude of one's heart---a heart which is bowed in worship regardless of any certain physical position.
That's why believers can choose to pray any place, anytime and in any position.
