How do we know Jesus is the true foundation for salvation?

Isaiah 28:16 proclaims that God lays a foundation stone in Zion, which is interpreted by New Testament writers as referring to Jesus Christ. This foundation is described as a 'tried stone' and 'precious cornerstone,' indicating its reliability and value for salvation. In 1 Peter 2:6, Peter echoes this truth by asserting that those who believe in Christ will not be put to shame. Thus, the apostolic witness confirms that Christ is the unique and essential foundation upon which all believers must stand.
