The possibilities of prayer are found in its allying itself with the purposes of God, for God’s purposes and man’s praying are the combination of all potent and omnipotent forces. More than this, the possibilities of prayer are seen in the fact that it changes the purposes of God. It is in the very nature of prayer to plead and give directions. Prayer is not a negation. It is a positive force. It never rebels against the will of God, never comes into conflict with that will, but that it does seek to change God’s purpose is evident. Christ said, “The cup which My Father hath given Me shall I not drink it?” and yet He had prayed that very night, “If it be possible let this cup pass from Me.” Paul sought to change the purposes of God about the thorn in his flesh. God’s purposes were fixed to destroy Israel, and the prayer of Moses changed the purposes of God and saved Israel. In the time of the Judges Israel were apostate and greatly oppressed. They repented and cried unto God and He said: “Ye have forsaken Me and served other gods, wherefore I will deliver you no more:” but they humbled themselves, put away their strange gods, and God’s “soul was grieved for the misery of Israel,” and he sent them deliverance by Jephthah. God sent Isaiah to say to Hezekiah, “Set thine house in order: for thou shalt die, and not live;” and Hezekiah prayed, and God sent Isaiah back to say, “I have heard thy prayer, I have seen thy tears; behold I will add unto thy days fifteen years.” “Yet forty days and Nineveh shall be overthrown,” was God’s message by Jonah. But Nineveh cried mightily to God, and “God repented of the evil that He had said He would do unto them; and He did it not.” The possibilities of prayer are seen from the divers conditions it reaches and the diverse ends it secures. Elijah prayed over a dead child, and it came to life; Elisha did the same thing; Christ prayed at Lazarus’s grave, and Lazarus came forth. Peter kneeled down and prayed beside dead Dorcas, and she opened her eyes and sat up, and Peter presented her alive to the distressed company. Paul prayed for Publius, and healed him. Jacob’s praying changed Esau’s murderous hate into the kisses of the tenderest brotherly embrace. God gave to Rebecca Jacob and Esau because Isaac prayed for her. Joseph was the child of Rachel’s prayers. Hannah’s praying gave Samuel to Israel. John the Baptist was given to Elizabeth, barren and past age as she was, in answer to the prayer of Zacharias. Elisha’s praying brought famine or harvest to Israel; as he prayed so it was. Ezra’s praying carried the Spirit of God in heart-breaking conviction to the entire city of Jerusalem, and brought them in tears of repentance back to God. Isaiah’s praying carried the shadow of the sun back ten degrees on the dial of Ahaz.
