Peter addresses Christians as to where they are and where they should be, and he uses the concept of a cornerstone to illustrate his point. The cornerstone is the one level stone set in the corner of a new structure, that all other little stones are lined up with and built on. That said, Jesus is our cornerstone. In this message Pastor Troy expounds on the fact that the church is comprised of many "stones" that make up one "body." Those disengaged are like "Rolling Stones", and those engaged are planted, solid, and have extraordinary support. That is what should be in terms of leaning on Christ as the main cornerstone, and assemble as a church body to remain strong and solid.
