Behold, I lay in Zion . . . a sure foundation;
whoever believes will not act hastily.
Actually, it’s not the skyline but the foundation line that upholds the buildings. It’s not the construction material upon which the building stands but rather the foundation. Often we think of something as fixed and immovable as a concrete slab when we talk about a foundation. Here, Paul is not talking about a particular doctrine, systematic theology, or the recorded words or deeds of the Lord Jesus, but rather he is talking about the living person of Jesus Christ Himself. He alone is the one tangible, concrete foundation who undergirds the church.
