And when thou prayest, thou shalt not be as the hypocrites are. For they love to pray standing in the synagogues and on the corners of the streets, that they may be seen by men. Verily I say unto you, they have their reward. But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father who is in secret; and thy Father who seeth in secret shall reward thee openly.
I, for one, would feel like a hypocrite. I don't lift my hands during daily worship, so why do it in church, where everyone could see? Of course, I'm not judging those who do. I think it's wonderful to see people do this.
Grace be with you,
