What does the Bible say about the formation of God's people?

Isaiah 43:21 declares, 'This people have I formed for myself; they shall show forth my praise.' This formation is not merely a physical act, but a spiritual work wherein God has chosen and shaped believers to reflect His glory. This text highlights God's sovereignty in choosing individuals who are seen as precious in His sight despite their sinfulness. These chosen ones are transformed by God's grace, becoming His people who are called to glorify Him in their lives, embodying the essence of true worship and praise.
