I desire, then, that in every place the men should pray, lifting up holy hands without anger or argument” (1 Tim 2:8).

Faith is not just a matter of the spirit; prayer is not just interior. The body must pray, too. Physical bearing plays a part in prayer, for it is with the body that we turn together to God in prayer. Paul speaks here of the lifting up of the hands, which reach out, as it were, for God. Today, too, we have need of such a reverent use of the body in prayer. Only when the body prays, too, do we pray with our whole self.
