This is the deepest meaning of all the sacrificial worship, as of Israel so of heathen nations--God Himself will provide a Lamb. The world had built altars, and Israel, by divine appointment, had its altar too. All these express the want which none of them can satisfy. They show that man needed a Sacrifice; and that Sacrifice God has provided. He asked from Abraham less than He gives to us. Abraham's devotion was sealed and certified because he did not withhold his son, his only son, from God. And God's love is sealed because He hath not withheld His only-begotten Son from us.
So this name that came from Abraham's grateful and wondering lips contains a truth which holds true in all regions of our wants. On the lowest level, the outward supply of outward needs; on a higher, the means of discharging hard duties and a path through sharp trials; and, on the highest of all, the spotless sacrifice which alone avails for the world's sins--these are the things which God provides.
2. So, note again on what conditions He provides them.
The incident and the name became the occasion of a proverb, as the historian tells us, which survived down to the period of his writing, and probably long after, when men were accustomed to say, 'In the mount of the Lord it shall be provided.' The provision of all sorts that we need has certain conditions as to the when and the where of the persons to whom it shall be granted. 'In the mount of the Lord it shall be provided.' If we wish to have our outward needs supplied, our outward weaknesses strengthened, power and energy sufficient for duty, wisdom for perplexity, a share in the Sacrifice which taketh away the sins of the world, we receive them all on the condition that we are found in the place where all God's provision is treasured. If a man chooses to sit outside the baker's shop, he may starve on its threshold. If a man will not go into the bank, his pockets will be empty, though there may be bursting coffers there to which he has a right. And if we will not ascend to the hill of the Lord, and stand in His holy place by simple faith, and by true communion of heart and life, God's amplest provision is nought to us; and we are empty in the midst of affluence. Get near to God if you would partake of what He has prepared. Live in fellowship with Him by simple love, and often meditate on Him, if you would drink in of His fulness. And be sure of this, that howsoever within His house the stores are heaped and the treasury full, you will have neither part nor lot in the matter, unless you are children of the house. 'In the mount of the Lord it shall be provided.' And round it there is a waste wilderness of famine and of death.
