A Christian cannot always hear, or always read, or always communicate, but he may pray continually. No place, no company, can deprive him of this privilege. If he be on the top of a house with Peter, he may pray; if he be at the bottom of the ocean with Jonah, he may pray; if he be walking in the field with Isaac, he may pray, when no eye seeth him; if he be waiting at the table with Nehemiah, he may pray, when no ear heareth him; if he be on the mountain with our Savior, he may pray; if he be in the prison with Paul, he may pray. Wherever he is, prayer will not be out of place, or wherever prayer is out of place, there he ought not to be. Every saint is God's temple, " and he that carrieth his temple about him (as Augustine has said) may go to prayer when he pleaseth." Indeed, to a Christian, every house is a house of prayer, every closet a chamber of presence, and every place he cometh to, an altar whereon he may offer the sacrifice of prayer.
