Ye also, as lively stones, are built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ. 1 Peter 2:5
Jesus is not only the Cornerstone of the church; He is also present in every one of the building blocks, because the Holy Spirit indwells every believer.
You’ve heard of someone being called a “chip off the old block.” That means he shares the traits and nature of his father. In a sense, every child of God is a chip off that Block. We are a chip off the chief Cornerstone. Listen to this:
Now therefore, you are no more strangers and foreigners, but fellow citizens with the saints, and of the household of God, and are built upon the foundation of the apostles and prophets, Jesus Christ Himself being the chief Cornerstone, in whom all the building fitly framed together groweth unto a holy temple in the Lord, in whom you also are built together for a habitation of God through the Spirit.
We are “fitly framed together,” and we’re growing into “a holy temple” in the Lord, a temple God Himself inhabits.
By ourselves we are not all that much. How many one-brick buildings have you seen? One stone can be easily tossed around, but if you take a lot of them and put them together, there is strength.
Our Lord is building us together to gain strength from one another. It is amazing what can happen when the body of Christ is unified.
