How can we trust that nothing built on Christ will be cast down?

The assurance that nothing built on Christ will be cast down is founded on His eternal nature and redemptive work. In 1 Peter 2:5, believers are described as ‘living stones’ built into a spiritual house, secure and impervious to destruction. Christ, as the cornerstone, is a solid foundation that provides lasting security against the judgment forthcoming in the world. While earthly structures and achievements may crumble, those who are alive in Christ will find their place in God's eternal kingdom, undisturbed by judgment as they are covered by His righteousness. This profound hope encourages believers to focus on Christ and His work, rejecting reliance on their own works for righteousness.
