The answer vows prompt obedience to yet undisclosed duty. God ever calls His servants to tasks which only by degrees are made known. So Paul in his conversion was bid to go into Damascus, and there learn what more he was to do. We must first put ourselves in God's hands, and then He will lead us round the turn in the road, and show us our work. We get it set for us bit by bit, but the surrender must be entire. The details of His will are revealed as we need them for the moment's guidance. Let us accept them in bulk, and stand to the acceptance in each single case! That is no obedience at all which says, 'Tell me first what you are going to bid me do, and then I will see whether I will do it.' The true spirit of filial submission says, 'I delight to do Thy will; now show me what it is.' It was a strange, long road on which Samuel put his foot when he answered this call, and he little knew where it was to lead him. But the blessing of submission is that we do not need to know. It is enough to see where to put our lifted foot. What comes next we can let God settle. The answer supplicated further light because of present obedience. 'Speak! for Thy servant heareth,' is a plea never urged in vain. The servant's open ear is a reason for the Lord's open lips. We may be quite sure that, if we are willing to hear, He is more than willing to speak; and anything is possible rather than that His children shall be left, like ill-commanded soldiers on a battlefield, waiting for orders which never come. 'If any man willeth to do His will, he shall know.' The sad prophecy which is committed to such apparently incongruous lips reiterates a former message by 'a man of God.' Eli was a kindly, and, in his way, good man, but wanting in firmness, and acquiescent in evil, partly, perhaps, from lack of moral courage and partly from lack of fervent religion. He is not charged with faults in his own administration of his office, but with not curbing his disreputable sons. The threatenings are directed, not against himself, but against his 'house,' who are to be removed from the high priestly office. Nothing less than a revolution is foretold. The deposition of Eli's family would shake the whole framework of society. It is to be utterly destroyed, and no sacrifice nor offering can purge it. The ulcer must have eaten deep which required such stern measures for its excision. The sin was mainly the sons'; but the guilt was largely the father's. We may learn how cruel paternal laxity is, and how fatal mischief may be done, by neglect of the plain duty of restraining children. He who tolerates evil which it is his province to suppress, is an accomplice, and the blood of the doers is red on his hands.
