Prayer is the highest privilege known to human beings. Jesus Christ, the Son of God, is the best guide for how to pray. To be a disciple is to pray. To be a growing disciple is to be growing in prayer.
Prayer itself is rooted in the inviting nature of the true and living God. It appreciates and applies grace in the most intimate and practical way. Because it taps into the Creator’s awesome power, there is no force on earth greater than the power associated with prayer. Because prayer is so effective, it is a key to all spiritual protection and progress. We need to place ourselves at the feet of Jesus to learn from Him. We seek to imitate the prayer life of Jesus, and so to share in His effectiveness. There is no greater teacher and example. Indeed, the way into God’s presence is paved by Jesus Himself. The privilege of prayer was bought at the highest cost to God and His Son.
As we pray Biblical prayers, their divine power will increase our strength. Romans 8:26-28, (Amplified Version) says, “So the Holy Spirit comes to our aid and bears us up in our weakness; for we do not know what prayer to offer nor how to offer it worthily as we ought, but the Spirit Himself goes to meet our supplication and pleads in our behalf with unspeakable yearnings and groanings too deep for utterance. And He who searches the hearts of men knows what is in the mind of the Holy Spirit - what His intent is because the Spirit intercedes and pleads [before God] in behalf of the saints according to and in harmony with God’s will. We are assured and know that [God being a partner in their labor], all things work together are [fitting into a plan] for good to those who love God and are called according to [His] design and purpose.”
