How do we know Jesus was sent by God?

We know Jesus was sent by God because, as described in Luke 4:18-19, He claims to be the fulfillment of the prophecy from Isaiah, where He is anointed by the Spirit to preach the gospel. The affirmation from the Father during Jesus' baptism, where He is called His beloved Son, further underscores this divine commission. Moreover, the fulfillment of Old Testament prophecies regarding the Messiah points to Jesus as the one truly sent from God, making it evident that His mission is both intentional and ordained by divine will.
