Why is Moses seen as a type of Christ in the sermon?

In the sermon, Moses is discussed as a type of Christ due to his role as an intercessor for the people of Israel. When the people sinned by creating the golden calf, Moses sought God's mercy on their behalf, asking that if their sin were not forgiven, he would be blotted out instead (Exodus 32:31-32). This parallels Christ's work, where He, too, intercedes for His people and takes upon Himself their sin, resulting in His death and resurrection. Moses exemplifies the sacrificial heart towards his people, much like Christ does for His elect.
