How do we know Jesus is the Christ according to the Bible?

The testimony of scripture and the witness of believers affirm Jesus as the Christ. In John 20:31, it states, 'But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.' This encapsulates the fundamental belief that recognizing Jesus as the anointed one, the Messiah, is not only foundational to faith but essential for eternal life. Believers like Peter and Martha also declare their faith, affirming that Jesus is indeed the Christ, the Son of the living God.
