The reason for the frustrating of David's desire, as here given, is his career as a warrior king. Not only was it incongruous that hands which had been reddened with blood should rear the Temple, but the fact that his reign had been largely occupied with fighting for the existence of the kingdom showed that the time for engaging in such a work, which would task the national resources, had not yet come. We may draw two valuable lessons from the prohibition. One is that it indicates the true character of the kingdom of God as a kingdom of peace, which is to be furthered, not by force, but in peace and gentleness. The other is that various epochs and men have different kinds of duties in relation to Christ's cause, some being called on to fight, and others to build, and that the one set of tasks may be as sacred and as necessary for the rearing of the Temple as the other. Militant epochs are not usually times for building. The men who have to do destructive work are not usually blessed with the opportunity or the power to carry out constructive work. Controversy has its sphere, but it is mostly preliminary to true 'edification.' In the broadest view all the activity of the Church on earth is militant, and we have to wait for the coming of the true 'Prince of peace' to build up the true Temple in the land of peace, whence all foes have been cast out for ever. To serve God in God's way, and to give up our cherished plans, is not easy; but David sets us an example of simple-hearted, cheerful acquiescence in a Providence that thwarted darling designs. There is often much self-will in what looks like enthusiastic perseverance in some form of service.
II. The charge to Solomon breathes no envy of his privilege, but earnest desire that he may be worthy of the honour which falls to him. Petitions and exhortations are closely blended in it, and, though the work which Solomon is called to do is of an external sort, the qualifications laid down for it are spiritual and moral. However 'secular' our work in connection with God's service may be, it will not be rightly done unless the highest motives are brought to bear on it, and it is performed as worship. The basis of all successful work is God's presence with us, so David prays for that to be granted to Solomon as the beginning of all his fitness for his task.
Next, David recalls to his son God's promise concerning him, that it may hearten him to undertake and to carry on the great work. A conviction that our service is appointed for us by God is essential for vigorous and successful Christian work. We must have, in some way or other, heard Him 'speak concerning us,' if we are to fling ourselves with energy into it.
The petitions in verse 12 seem to stretch beyond the necessities of the case, in so far as building the Temple is concerned. Wisdom and understanding, and a clear consciousness of the duty enjoined on him by God in reference to Israel, were surely more than that work required. But the qualifications for God's service, however the manner of service may be concerned with 'the outward business of the house of God,' are always these which David asked for Solomon. The highest result of true 'wisdom and understanding' given by God is keeping God's law; and keeping it is the one condition on which we shall obtain and retain that presence of God with us which David prayed for Solomon, and without which they labour in vain that build. A life conformed to God's will is the absolutely indispensable condition of all prosperity in direct Christian effort. The noblest exercise of our wisdom and understanding is to obey every word that we hear proceeding out of the mouth of God.
