How do we know Christ is our true King?

The declaration of Christ as King comes from His own words during His trial, where He acknowledges His kingdom as not of this world. This establishes the reality that His reign is spiritual, obtained through the work of the Holy Spirit in the hearts of believers. Just as Gideon represented God's deliverance in the Old Testament, Christ fulfills that role perfectly. Reformed theology upholds that through faith in Him, believers are called children of the King, living under His sovereign rule that is characterized by grace and love, not merely law.
