"Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Messiah Yeshua for you."
1 Thessalonians 5:16-18, 'Messianized' ESV
The Word of God is clear that prayer is a characteristic of a disciple. In the gospels we see Yeshua doing a lot of praying. If we want to follow Him and live as He did, then a lifestyle of prayer should be on our 'To-Do Lists."
Praying at all times is something that God wants us to do. We can therefore be aligned with the will of God by communicating with Him; perhaps at set prayer times, or throughout the day, or just whenever God speaks to us. We must be open to the Spirit of God.
Finally, we want to remember that prayer is not a "To-Do List" we give to God, though we certainly do ask our Lord for help. We also take time in these gatherings to give rightful praise to Our Creator who answers prayer. It is not the "power of prayer" that we seek, but rather the power of God.
