1 Peter 2:4-8 As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture:
“Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”
So the honor is for you who believe, but for those who do not believe,
“The stone that the builders rejected has become the cornerstone,”
and
“A stone of stumbling, and a rock of offense.”
They stumble because they disobey the word, as they were destined to do.
There is no dispute among people who believe the truth.
“Jesus is the chief cornerstone.”
Yes, which, in ancient times was the first stone laid in the foundation of a structure. It is only in modern days that it is an ornamental part of the structure itself:
“The cornerstone (or foundation stone) concept is derived from the first stone set in the construction of a masonry foundation, important since all other stones will be set in reference to this stone, thus determining the position of the entire structure.
Over time a cornerstone became a ceremonial masonry stone, or replica, set in a prominent location on the outside of a building, with an inscription on the stone indicating the construction dates of the building and the names of architect, builder and other significant individuals.”
