A.B. Simpson emphasizes the dual nature of Jesus Christ as both the righteous King and the compassionate Man, drawing from Isaiah 11. He contrasts the oppressive reign of kings like Ahaz with the promise of a King who will rule in righteousness and justice, providing hope and refuge. Simpson highlights that Jesus, as the Man, embodies human empathy and understanding, offering shelter from sin and life's storms. He encourages believers to reflect Christ's love and support to others, becoming sources of refuge and refreshment in a weary world. Ultimately, the sermon calls for a deeper relationship with Christ, who is both our King and our compassionate Savior.
