The call to watch and pray is strongly encouraged throughout the Bible as a safeguard against evil, particularly at times when there is a sense of urgency and/or an awareness of being vulnerable.
“Let my prayer be counted as incense before you, and the
lifting up of my hands as the evening sacrifice!” Psalm 141:2 ESV
verse from a psalm of David expresses his desire, and the desire all true
worshippers in spirit and in truth, that our prayers and praise be an
expression of lives that are constantly devoted to pleasing God.
