You also, as living stones, are built up as a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ.
This verse helps us appreciate how much we need each other as Christians. God has a purpose for all of us to fulfill that we cannot fulfill individually. The Christian who is not working in relationship with other Christians as fellow stones, as well as with Jesus Christ as his or her foundation, cannot fulfill God’s complete purpose for him or her. While every Christian has an individual purpose, we also have a corporate purpose that we cannot fulfill unless we take our place in the community of Christians that is the church. Peter explained this purpose more fully below, but here he revealed that it involves worship and service (cf. Romans 12:1; Hebrews 13:15-16; Philippians 4:18).
