Andrew Murray emphasizes the profound need for believers to learn how to pray effectively, drawing from the disciples' request to Jesus, 'Lord, teach us to pray.' He highlights that true prayer is a divine art that connects us with God and is essential for spiritual power and life. Murray encourages Christians to seek Jesus as the ultimate teacher of prayer, recognizing that it requires humility, dependence on the Holy Spirit, and a willingness to learn. He reassures that through persistent prayer and a teachable spirit, believers can grow in their ability to intercede and experience the fullness of God's promises. Ultimately, he calls for a renewed commitment to prayer, inviting all to enroll in the school of prayer that Jesus offers.
