“Consequently, you are no longer foreigners and aliens, but fellow citizens with God’s people and members of God’s household, built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone.”
(Ephesians 2:19-20)
Ephesians 2 calls Jesus the “chief cornerstone,” which provides a picture of how Jesus is the center of life. In construction, a cornerstone is the very first stone laid at the corner of where two walls will meet; it is the most important part of a new building. Everything else in the building is based on that first stone—the cornerstone. Basically, without the right cornerstone, it doesn’t matter how good everything else you do is. You will not have stability or permanent progress because your cornerstone will either crumble under all the pressures of life or lead to things being out of place and crooked.
God gave Jesus as your cornerstone. Jesus is meant to join you, a sinful person, to a Holy God through His grace and mercy. Jesus is also meant to be the first and central thing you depend on to bring together all the different parts of your life every day. He is the only true cornerstone that is strong enough to handle all of the pressures of life and all of the uneven circumstances and turmoil of this world.
