A Christian cannot always hear, or read, or always communicate, but he may pray continually. No place, no company, can deprive him of this privilege.
If he is on the housetop with Peter, he may pray; if he is at the bottom of the ocean with Jonah, he may pray; if he is walking in the field with Isaac, he may pray, when no eye sees him; if he is waiting at the table with Nehemiah, he may pray, when no ear hears him; if he is on the mountain with our Savior, he may pray; if he is 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.
Indeed, to a Christian, every house is a house of prayer, every closet a chamber of presence, and every place he comes to, an altar whereon he may offer the sacrifice of prayer.
