Jesus is the stone you builders rejected, which has become the cornerstone. Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.
‭‭Acts‬ ‭4‬:‭11‬-‭12‬ ‭NIV‬‬

A cornerstone serves as a foundation or starting point for a building, monument, or other structure. It is typically the first stone set in the construction of a building, and plays a significant role in the overall stability and integrity of the structure.

It represents the values, principles, or beliefs upon which the building or institution is founded.
