But a much more important factor in determining his character and shaping his life was the religious awakening in which Samuel had so prominent a share. Not a word is said anywhere of the manner in which David's heart was first turned to God; but this must have been in his earliest years. We think of David as we think of Samuel, or Jeremiah, or Josiah, or John the Baptist, as sanctified to the Lord from his very childhood. God chose him at the very outset in a more vital sense than He afterwards chose him to be king. In the exercise of that mysterious sovereignty which we are unable to fathom, God made his youthful heart a plot of good soil, into which when the seed fell it bore fruit an hundredfold. In strong contrast to Saul, whose early sympathies were against the ways and will of God, those of David were warmly for them. Samuel would find him an eager and willing listener when he spoke to him of God and His ways. How strange are the differences of young persons, in this respect, when they come first under the instructions of a minister or other servant of God! Some so earnest, so attentive, so impressed; so ready to drink in all that is said; treasuring it, hiding it in their hearts, rejoicing in it like those that find great spoil. Others so hard to bring into line, so glad of an excuse for absence, so difficult to interest, so fitful and unconcerned. No doubt much depends on the skill of the teacher in working upon anything in their minds that gives even a faint response to the truth. And in no case is the aversion of the heart beyond the power of the Holy Spirit to influence and to change. But for all that, we cannot but acknowledge the mysterious sovereignty which through causes we cannot trace makes one man so to differ from another; which made Abel so different from Cain, Isaac from Ishmael, Moses from Balaam, and David from Saul.
Was David at any time a member of any of the schools of the prophets? We cannot say with certainty, but when we ponder what we read about them it seems very likely that he was. These schools seem to have enjoyed in an eminent degree the gracious power of the Holy Spirit. The hearts of the inmates seem to have burned with the glow of devotion; the emotions of holy joy with which they were animated could not be restrained, but poured out from them, like streams from a gushing fountain, in holy songs and ascriptions to God; and such was the overpowering influence of this spirit that for a time it infected even cold-hearted men like Saul, and bore them along, as an enthusiastic crowd gathers up stragglers and sweeps them onward in its current. It seems highly probable that it was in connection with these institutions, on which so signal a blessing rested, that the devotional spirit became so powerful in David afterwards poured out so freely in his Psalms. For surely he could not be in the company of men who were so full of the Spirit without sharing their experience and pouring forth the feelings that stirred his soul.
We all believe in some degree in the law of heredity, and find it interesting to trace the features of forefathers, physical and spiritual, in the persons of their descendants. The piety, the humanity, and the affectionateness of Boaz and Ruth form a beautiful picture in the early Hebrew history, and seem to come before us anew in the character of David. Boaz was remarkable for the fatherly interest he took in his dependants, for his generous kindness to the poor, and for a spirit of gentle piety that breathed even through his secular life. Was it not the same spirit that dictated the benediction, "Blessed is he that considereth the poor; the Lord will deliver him in time of trouble"? Was it not the same interest in the welfare of dependants that David showed when "he dealt among the people, even the whole multitude of Israel, as well to the women as to the men, to every one a cake of bread, and a good piece of flesh, and a flagon of wine? Ruth again was remarkable for the extraordinary depth and tenderness of her affection; her words to Naomi have never been surpassed as an expression of simple, tender feeling: "Entreat me not to leave thee, nor to return from following after thee; for whither thou goest I will go, and where thou lodgest I will lodge; thy people shall be my people, and thy God my God." Does not this extraordinary tenderness seem to have fallen undiminished to the man who had such an affection for Jonathan, who showed such emotion on the illness of his infant child, and poured out such a flood of anguish on the death of Absalom? The history of Boaz and Ruth would surely take hold very early of his mind. The very house in which he lived, the fields where he tended his sheep, every object around him, might have associations with their memory; aged people might tell him stories of their benevolence, and pious people give him traditions of their godliness, and thus an element would be contributed to a character in which the tenderness of a woman and the piety of a saint were combined with the courage and energy of a man.
