How do we know Christ being a stumbling stone is true?

Scripture points to the reality that Christ serves as a stumbling stone for many who reject Him. In 1 Peter 2:7-8, it states that the very stone the builders rejected has become the chief cornerstone and a stone of stumbling for the disobedient. This duality illustrates the sovereignty of God in the election of grace, where those who do not see Christ's true worth stumble over Him due to their pride and self-righteousness. The rejection signifies a deeper issue of the human heart, which remains unable to see its need for a Savior unless God intervenes with grace.
