"And a vision appeared to Paul in the night; There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us." (Acts 16:9)

God spoke to Paul at this juncture through a vision. Such a vision was needed because Paul was doing a new thing. The history of Christianity was changing. A stupendous thing was going to happen. In this world, whenever a great change came about in religion, man was given a great revelation. Paul was asked to go to Europe of which place he was not thinking at all. Now God met him. Why is it God does not appear to us that way? Is God not willing to help us? There is no partiality with God. God gives His revelations to those who are utterly obedient to Him. If you are doing what you know to be wrong God cannot be with you. Mere knowledge is different from obedience. If you follow the truth you know, God will certainly reveal Himself to you. God will meet men in extraordinary ways. God has created the whole universe for you. If we obey, God is willing to do anything for us. St. Paul was one who followed the knowledge he had. At first when he thought Christ was not true, he fought Christianity with all his might. God knew that if he knew Christ he would follow Him. God met him in the way to Damascus and Paul obeyed Him. Then he went away to Arabia to pray and know more about God. Man meets God on the wings of prayer. As Paul was praying, great revelations began to come to him. He was always in the spirit. If we are absolutely obedient, we will be always in the spirit. "Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints:" (Ephesians 6:18). "Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life" (Jude 21). "And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God" (Galatians 6:16).
