But then this heavenly food was, of necessity, a test of Israel's condition, as we read, "That I may prove them, whether they will walk in My law or no." It needed a heart weaned from Egypt's influences, to be satisfied with or enjoy "bread from heaven." In point of fact, we know that the people were not satisfied with it, but despised it, pronounced it "light food," and lusted for flesh. Thus they proved how little their hearts were delivered from Egypt, or disposed to walk in God's law. "In their hearts they turned back again into Egypt." (Acts vii. 39.) But instead of getting back thither, they were ultimately carried away beyond Babylon. (Acts vii. 43.) This is a solemn and salutary lesson for Christians. If those who are redeemed from this present evil world do not walk with God in thankfulness of heart, satisfied with His provision for the redeemed in the wilderness, they are in danger of falling into the snare of Babylonish influences. This is a serious consideration. It demands a heavenly taste to feed on bread from heaven. Nature cannot relish such food; it will ever yearn after Egypt, and therefore it must be kept down. It is our privilege, as those who have been baptized unto Christ's death, and "risen again through the faith of the operation of God," to feed upon Christ as "the bread of life which came down from heaven." This is our wilderness food--Christ as ministered by the Holy Ghost, through the written Word; while, for our spiritual refreshment, the Holy Ghost has come down as the precious fruit of the smitten Rock--Christ, as smitten for us. Such is our rare portion in this desert world.
