ἀδιαλείπτως προσεύχεσθε
In just two words, 1 Thessalonians 5:17 encapsulates a powerful call to a life immersed in prayer. The Greek construction is short but loaded with theological and spiritual depth. It emphasizes not only the frequency of prayer but its continual rhythm as an ongoing state of relationship with God.
Grammatical Foundations
ἀδιαλείπτως is an adverb meaning “unceasingly,” “without interruption,” or “constantly.” It modifies the manner of the verb that follows. The word is used in Greek literature to describe something occurring at regular intervals or without pause, such as a persistent cough or continuous activity.
προσεύχεσθε is the present middle/passive imperative, 2nd person plural, from προσεύχομαι—“to pray.” The present imperative form expresses ongoing, habitual action: “be praying continually,” not just once or at specific times. The imperative mood makes it a command, not a suggestion.
Exegetical and Theological Implications
This verse calls believers into a lifestyle, not merely an action. Prayer here is not confined to moments of crisis or designated hours but becomes the heartbeat of Christian existence. The adverb ἀδιαλείπτως invites believers to maintain a posture of open communication with God throughout all of life.
Theologically, this aligns with the idea of abiding in Christ (John 15) and walking in the Spirit. It also implies that prayer is more than words—it is attentiveness, dependence, and inner communion with God that spans every context of life.
Linguistic and Historical Perspectives
The word ἀδιαλείπτως appears in both classical and Koine Greek and was often used in medical or military contexts to describe vigilance and persistence. In Paul’s letters, it emphasizes spiritual perseverance (cf. Romans 1:9; 1 Thess 1:3).
προσεύχομαι is the most common New Testament verb for prayer and often includes the nuance of reverence and worship. The use of the present imperative emphasizes not a moment of prayer, but an orientation of the entire life toward God.

The Verse as a Paradigm of Koine Greek Richness
1 Thessalonians 5:17 is a shining example of how Koine Greek can say much in few words. Through one adverb and one imperative, Paul calls the believer into a life of continual divine connection. This isn’t just instruction—it’s invitation: a rhythm of grace marked by unceasing prayer.
