Indeed!
Matthew 6:6 "But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly."
Christ disdained those who made prayer a public spectacle. If we pray to be seen those prayers will never be answered.
James 4:3 "Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts."
