In his sermon, "Who is This?", Dr. Maxwell Ferguson delves into the significance of Jesus' triumphant entry into Jerusalem, known as Palm Sunday, explored through Matthew 21:6-11. The sermon emphasizes Jesus' identity and the importance of recognizing it, further illustrated by Dr. Ferguson's childhood story about the need to identify a late-night visitor before opening the door. He connects this to the inquiry of the people of Jerusalem regarding Jesus: "Who is this?", reflecting that while some proclaimed him the Messiah, others familiar with him as a Galilean were left in confusion.

Throughout the sermon, Dr. Ferguson elaborates on the public declaration of Jesus’ kingship, its fulfillment of the prophecy as narrated in Zechariah 9:9, and the resulting turmoil in the city. He discusses Jesus’ arrival as a different kind of a king; not a worldly ruler but a servant, a sacrifice as foretold by prophets. The teachings of Jesus about dying and his ultimate act of sacrifice to conquer sin and death are highlighted as the major aspects of his kingship.

Further, Dr. Ferguson challenges the misconceptions about Jesus' kingship, including the expectancy for him to vanquish the Romans and restore Israel's national greatness. He clarifies that Jesus intended to defeat sin and death, not earthly enemies, emphasizing the need to understand Jesus’ kingship in line with scripture. In conclusion, the congregation is invited to accept Jesus as their ruler, celebrate him during Easter, and to rely on his sacrifice for salvation. Concluding with an altar call, Dr. Ferguson prays for the congregation to let God reign in their lives and transform them in Jesus’ likeness. Throughout, the sermon maintains a recurrent theme of Jesus' sacrifice, humility, the avoidance of misconceptions about his kingship, and the ultimate triumph over sin and death.
