The quotation of Isaiah 42:1 in Matthew 12:18 shows that Jesus, who knows all things and heals all people (Matthew 12:18), can do this because he is God’s promised, chosen, and beloved servant, and God is with him in his Spirit. Jesus’ appearance brings the last hour for the nations, proclaiming God’s judgment to the world. While he has not yet executed that judgment, Jesus’ appearance shows that it is near.
The quotation of Isaiah 42:1 in Isaiah 42:1 indicates that Jesus, who knows all things and heals all people (Matthew 12:18), can do this because he is God’s promised and chosen servant. God is with him. Because he was anointed with God’s Spirit, he can perform these deeds of mercy. And he is the decisive moment for the whole world (all nations). With his appearance, the last hour dawns for the nations. When God sends his beloved, this servant, by his coming, proclaims the moment on which God will bring judgment to the world. It is true that he has not yet executed that judgment, but Jesus’ appearance demonstrates that it is near. He is God’s last word for the nations of the world.1
18 Voici mon serviteur que j'ai choisi,Mon bien-aimé en qui mon âme a pris plaisir.Je mettrai mon Esprit sur lui,Et il annoncera la justice aux nations.
