"Faith is the key of happiness; use it at the gates of the Lord's house, and chambers of bliss shall be opened unto you. If your religion only admits you into vaults and dungeons it must be very incomplete. Christ comes from ivory palaces, and leads his chosen into banqueting houses."- Spurgeon's Sermon Notes
