What is the analogy of the chief cornerstone thrown into a vacant lot?
The analogy pictures the chief cornerstone, Christ, rejected by Israel and cast into a vacant lot, where weeds grew and people stumbled over it. Though temporarily set aside, it will not remain covered forever; it will return to take its rightful place as the chief cornerstone of God's dealing with Israel and the world.
Les teaches that Israel, as the builders, disallowed the stone and cast it aside. The chief cornerstone was thrown into a vacant lot, weeds grew up around it, and those passing by stumbled over it. But that stone of stumbling will not stay out covered with weeds forever. The day is coming when it will return and take its place as the chief cornerstone of God's dealing with the nation of Israel as well as the world as a whole. This illustrates Israel's rejection of Christ and His future restoration as the cornerstone.
