A life is to appear. It is not an interposition or interpolation. No event, no life is ever thrust into an age without relation to the past; no purpose is formed in the hour of a certain prophecy. For Samson as for every actor distinguished or obscure upon the stage of the world the stars and the seasons have co-operated and all that has been done under the sun has gone to make a place for him. One who knows this can speak strongly and clearly. One who knows what hinders and what is sure to aid the fulfilment of a great destiny can counsel wisely. And so the angel of Jehovah, a messenger of the spiritual covenant, is no mere vehicle of a prediction he does not understand. Without hesitation he speaks to the woman in the field of what her son shall do. By the story of God's dealings with Israel, by the experiences of tribe and family and individual soul since the primitive age, by the simple faith of these parents that are to be and the honest energy of their humble lives he is prepared to announce to them their honour and their duty. "Thou shalt bear a son and he shall begin to deliver Israel." The messenger has had his preparation of thought, inquiry deep devout and pondering, ere he became fit to announce the word of God. No seer serves the age to which he is sent with that which costs him nothing, and here as elsewhere the law of all ministry to God and man must apply to the preparation and work of the revealer. The personality of the messenger was carefully concealed. "A man of God whose countenance was like that of an angel of God very terrible"--so runs the pathetic, suggestive description; but the hour was too intense for mere curiosity. The honest mind does not ask the name and social standing of a messenger but only--Does he speak God's truth? Does he open life? There are few perhaps, to-day, who are simple and intelligent enough for this; few, therefore, to whom divine messages come. It is the credentials we are anxious about, and the prophet waits unheard while people are demanding his family and tribe, his college and reputation. Are these satisfactory? Then they will listen. But let no prophet come to them unnamed. Yet of all importance to us as to Manoah and his wife are the message, the revelation, the announcement of privilege and duty. Where that divine order is disclosed which lies too deep for our own discovery but once revealed stirs and kindles our nature, the prophet needs no certification.
