What does the Bible say about Christ as the sure foundation?

Isaiah 28:16 proclaims that God has laid a sure foundation, identified as Christ, a precious cornerstone. This foundation is established by God's eternal covenant, ensuring that all who believe in Him will find their salvation secure and unwavering. In times of trial, believers can trust that their faith rests upon a solid and immovable foundation, signifying eternal safety and hope. The passage further resonates with the truth found in Romans 4:16, emphasizing that this foundation is built on faith and grace, not on human works or righteousness.
