How do we know Jesus is the Son of God and the Son of Man?

We can affirm that Jesus is both the Son of God and the Son of Man through His resurrection, which validates His claims. Acts 2:23-36 details how God raised Jesus from the dead, thus demonstrating His authority over sin and death. This event not only affirms His identity as the promised Messiah but also fulfills the Old Testament prophecies regarding the nature of the Messiah, who would bear the sins of His people and reign in glory. Through the resurrection, Jesus is declared Lord and Christ, confirming His unique position as the one mediator between God and humanity.
