How do we know that Jesus is God's servant from the womb?

In Isaiah 49, God's declaration that Jesus was called from the womb underscores the doctrine of the incarnation and the eternal plan of redemption. Verses 1-2 illustrate that Jesus was appointed to be the servant of the Lord, destined to accomplish God’s purposes. This preordained role emphasizes the significance of Christ's servanthood, reflecting the perfect obedience and submission to God’s will. It establishes the theological foundation for understanding Christ's mission as the Mediator between God and man.
