1 Peter 2 tells us that Jesus is the chief cornerstone of God's temple.  He is the only appropriate foundation for your life.  If you get the foundation of your life wrong, everything else will be off.  If you believe in Him, you become a living stone, building on what Jesus did.  You become a priest in God's temple.  This is the idea of the priesthood of all believers.  If you are a Christian, you are a priest, and you can minister to other.  And then he tells us that because Jesus suffered for doing what was right, we will also suffer for doing what is right.
