Bringing the case closer home to himself the Psalmist makes this declaration as to his practice: “With my whole heart have I sought thee; O let me not wander from thy commandments.” And further on, giving us his prayer for a wise and understanding heart, he tells us his purposes concerning the keeping of God’s law: “Give me understanding and I shall keep thy law; Yea, I shall observe it with my whole heart.” Just as it requires a whole heart given to God to gladly and fully obey God’s commandments, so it takes a whole heart to do effectual praying. Because it requires the whole man to pray, praying is no easy task. Praying is far more than simply bending the knee and saying a few words by rote. “’Tis not enough to bend the knee, And words of prayer to say; The heart must with the lips agree, Or else we do not pray.” Praying is no light and trifling exercise. While children should be taught early to pray, praying is no child’s task. Prayer draws upon the whole nature of man. Prayer engages all the powers of man’s moral and spiritual nature. It is this which explains somewhat the praying of our Lord described as in Hebrews 5:7: “Who in the days of his flesh, when he had offered up prayers and supplications, with strong crying and tears, unto him that was able to save him from death, and was heard in that he feared.” It takes only a moment’s thought to see how such praying of our Lord drew mightily upon all the powers of His being, and called into exercise every part of His nature. This is the praying which brings the soul close to God and which brings God down to earth. Body, soul and spirit are taxed and brought under tribute to prayer. David Brainerd makes this record of his praying: “God enabled me to agonise in prayer till I was wet with perspiration, though in the shade and in a cool place.” The Son of God in Gethsemane was in an agony of prayer, which engaged His whole being: “And when he was at the place, he said unto them, Pray ye that ye enter not into temptation. And he was withdrawn from them about a stone’s cast, and kneeled down and prayed, saying, Father, if thou be willing, remove this cup from me; nevertheless, not my will, but thine, be done. And there appeared an angel unto him, from heaven, strengthening him. And being in an agony, he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground.” Luke 22:40-44. Here was praying which laid its hands on every part of our Lord’s nature, which called forth all the powers of his soul, His mind and His body. This was praying which took in the entire man. Paul was acquainted with this kind of praying. In writing to the Roman Christians, he urges them to pray with him after this fashion:
