Prayer is the way in which the children of God express their needs from the depths of the heart to the Lord Jesus Christ. The Holy Spirit; Whom dwells within each and every person, records the prayer made and pleads to the Son directly with words and intense desire that is far beyond our understanding. Prayer is powerful and it can indeed move mountains aside, only if of course the Lord deems it necessary. Also, it is a faithful act, not one lacking in faith. The Lord Jesus Christ was very clear that the prayer must be one made in genuine faith, else He will not be inclined to answer that prayer.
