If any man will do the will he shall know of the doctrine.
What a man receives must depend upon what he is able to receive. [illustration. The sponge absorbs more water than the wood, because its pores are more open.] To receive the light of revelation the spiritual pores must be well opened; and this depends upon inward conditions—the will to obey, followed by obedience. Here a revelation is impending. Notice—
I. READINESS OF THE WOULD-BE RECIPIENTS. Moses had declared the Divine will. The hearers might have been indifferent, or they might have been disheartened by the stringency of the injunctions. In either case, through their imperfect condition, more perfect light must have been delayed. For a little, however, they were rapt out of self; and though, it may be, the momentary enthusiasm did not pierce clouds which years only could disperse, yet they were ready for the moment to gain a glimpse, at any rate, of the Divine glory. "All the words which the Lord hath said will we do:" such was the utterance of the people's disposition at the moment. Temporary inclination, however, is not everything; at best it only marks out the way along which effort may compel habit. For a nation to speak with "one voice" is something; but it needs discipline and training to secure the "one heart" as well. The first step towards securing this has next to be taken:—
II. READINESS CONFIRMED AND ACCEPTED. A record needed to impress the memory; a sacramental symbol to impress the imagination.
1. The record. "Moses wrote all the words of the Lord," and, when he had read what he had written, the people confirmed their previous promise (Exodus 24:7). A written reminder of the covenant as accepted by them was all-important; a dying enthusiasm goes hand in hand with a waning memory; only a record which will revive the memory can avail to rekindle the enthusiasm. Our own experience illustrates this. The diary, the marked Bible—what a suggestive eloquence they have, not only to remind of old times, but to re-awaken old feelings!
2. The sacramental symbol. Burnt-offerings, the outward sign of dedication and obedience; peace offerings, the outward sign of gratitude and thanksgiving. Half the blood sprinkled on the people and half on the altar, symbol of the union between man and God so long as his commands were thankfully obeyed. So long as man is in the flesh he needs such sensible and visible emblems. His senses are a function of himself; to lay hold of them is to lay hold of him through them. The Bible is our record of what God requires of us; but baptism and the Lord's Supper give outward expression to the teaching of the Bible. Each confirms the influence of the other; we need both to support our resolutions.
III. THE PARTIAL REVELATION. The people had expressed their willingness to obey; and, further, they had openly confirmed that expression. Time, however, was needed to test and strengthen their resolution: they could not be admitted to the full blaze of light merely because, in partial darkness, they had for a little gazed towards its dawning. A few are selected to represent the multitude (Exodus 24:1, Exodus 24:9-11); and even of these few, not all are admitted to equal nearness. Enough is revealed to help faith, more would probably have only injured its growth. [illustration: Plants are kept from too much light until they are firmly rooted.] Faith, here, needed rooting: until that was accomplished an economy of reserve was necessary.
Concluding considerations.—
1. The honest promise of obedience is accepted by God as of moral value. He encourages sincerity by glimpses of the reward in store.
2. Only obedience tested by difficulty can win the realisation of the beatific vision. The people must share the life-long training of Moses before they can enjoy with the like freedom his privilege of intimacy with God. Willingness to obey brings knowledge; but full knowledge comes with full obedience.—G.
