“ . . . upon this rock I will build my church . . .”
Essentially Jesus is saying, “I will design and construct My church. I am the builder and the designer, so I will supply the material. What I build, only I can build. I will build My church.” He goes on to make another statement relating to construction, and that is one of possession: “My church.” That is, He is the owner of the church. The church belongs to Him. He has the key and the code to the church, and He is the owner of it.
