What does the Bible say about the posture of prayer?

The Bible highlights that while physical posture, such as kneeling or standing, can signify humility and reverence in prayer, the essential aspect is the sincerity and disposition of the heart toward God. In Ephesians 3:14, Paul bows his knees, showing submission and humility before the Father as an act of reverence. However, true prayer must stem from a heartfelt devotion, as Jeremiah 29:13 reminds us that we will find God when we seek Him with our whole hearts. Therefore, whether standing, kneeling, or in any other position, the internal attitude of sincerity and humility is what God desires in our communication with Him.
