How do we know the doctrine of representation is true?

The concept of representation finds its roots in the biblical narrative of Exodus, where Moses serves as a mediator between God and the Israelites. In Exodus 24:2, God instructs that Moses alone may come close to Him, establishing Moses as a unique representative. This typology exemplifies Christ, who is our ultimate representative and substitute. Just as the Israelites could only interact with God through Moses, believers can approach God through Christ. Thus, the doctrine is affirmed through Scripture as a central theme of how God works through representatives to achieve His purposes, ultimately fulfilled in Jesus Christ.
