Therefore it is also contained in the Scripture, “Behold, I lay in Zion a chief cornerstone, elect, precious, and he who believes on Him will by no means be put to shame.” 1 Peter 2:6
The cornerstone is the first stone laid down in the construction of a building.
It is the reference point for every other stone.
The builders constantly measure against the stone, checking that the straight lines are square and true, and that the vertical lines are upright.
The slightest error can translate into instability and eventual failure of the entire structure.
Jesus Christ is the perfect cornerstone.
The entire Kingdom of Heaven is built upon Him.
We can build our lives using Jesus Christ as our reference.
If we do, our lives will be straight and true and upright.
Or we can use something else, and take our chances.
