A proper understanding of corporate worship is that it is rooted in God who calls His body together into the official assembly of public worship. The assembly comes together to meet with God as God's covenant people. Therefore, the worship service is not directed by personal preferences, but by God who calls His people as His own.
In chapter 1, John Frame wants to give an answer to the question, “What is worship?" He emphasizes that it should be God-centred, gospel-centred, and it is worship of the triune God. He also explores how in worship attention should be given to the relationship with our fellow believers and society as a whole. Frame also explains his understanding of worship in a narrow and broader meaning.
