We know Jesus is a sure foundation because He is described as a tried and precious cornerstone in Scripture, who fulfills God's promises.
The certainty of Christ as our foundation lies in His identity as a tried stone and a precious cornerstone, as noted in Isaiah 28:16. Christ was tested and tried by both men and through divine wrath, ultimately proving His worth as the cornerstone of our faith. When He declared 'It is finished,' He established Himself as the only effective foundation for salvation. This declaring of Jesus as the sure foundation is not based on human reasoning but on divine revelation, emphasizing that God's choice and design for salvation lies solely in His Son.
