Why is David considered a picture of Christ?

Throughout the sermon, David is identified as a foreshadowing of Christ in several ways. First, like Christ, David is connected with sheep, symbolizing him as a shepherd. In John 10, Jesus identifies Himself as the good shepherd, who lays down His life for the sheep. Secondly, David engages in battle against Goliath, paralleling Christ's ultimate victory over sin and death. Finally, David's servant heart reflects the servanthood of Christ, who came not to be served but to serve and give His life as a ransom for many, which is foundational in understanding his mission in redemption.
