How does God's sovereignty relate to Christ being both a cornerstone and a stumbling stone?

God's sovereignty plays a critical role in Christ's dual function as both the chief cornerstone and a stumbling stone. His choice to elevate Christ as the cornerstone reflects His purpose for salvation, while simultaneously allowing Him to be a stumbling stone to those who seek righteousness through their own efforts (Romans 9:31-33). This illustrates God's supreme authority in deciding who will embrace Christ and who will reject Him. The contrasting responses to Christ reveal the depths of human depravity and the necessity of divine grace in recognizing and accepting Him.
