Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you. — I Thessalonians 5:16-18.
We are told to “pray without ceasing” in the Bible. John MacArthur, in Pulpit Magazine, explores this question:
Unceasing, incessant prayer is essential to the vitality of your relationship to the Lord and your ability to function in the world. But exactly what does it mean to pray without ceasing?
The first time someone hears about the concept of praying without ceasing it may conjure up the image of Christians walking around with their hands folded, heads bowed, and eyes closed, bumping into things. While certain postures and specific times set aside for prayer have an important bearing on our communication with God, to “pray at all times” obviously does not mean we are to pray in formal or noticeable ways every waking moment. And it does not mean you’re supposed to devote yourself to reciting ritualistic patterns and forms of prayer.
To “pray without ceasing” refers to recurring prayer, not nonstop talking. Prayer is to be a way of life — you’re to be continually in an attitude of prayer. It is living in continual God-consciousness, where everything you see and experience becomes a kind of prayer, lived in deep awareness of and surrender to Him. It should be instant and intimate communication — not unlike that which we enjoy with our best friend.
