How do we know Jesus is the Lord of all?

The affirmation of Christ as the Lord of all is rooted in both His divine identity and the authority granted to Him by God the Father. In John 17:2, we see that the Father has given the Son authority over all people, asserting His control and lordship. This is complemented by the declaration in Matthew 28:18, where Jesus states that all authority in heaven and on earth has been given to Him. Thus, Jesus' role as both God and the appointed mediator signifies that He possesses ultimate authority and control over all of creation, further highlighting His position as the sovereign Lord.
