PRIDE:
SPIRITUAL; PRAYER: WRONG USE OF

Nothing is so vital as prayer, yet a reputation for being a mighty prayer warrior is probably the most perilous of all reputations to have. No form of selfishness is so deeply and dangerously sinful as that which glories in being a man of prayer. It comes near to being self-worship; and that while in the very act of worshiping God.

Matthew 6:1–6; Matthew 23:5
