How do we know that Christ rules and reigns over creation?

The sermon emphasizes that Christ's rule is established not only through scripture but also through His actions as the exalted mediator who has ascended to God's right hand. Colossians 3:1 encourages believers to seek the things above, affirming that Christ is seated in authority. His kingship is further underscored by the historical events of His death, resurrection, and ascension, which demonstrate His ultimate authority over not only spiritual matters but also earthly affairs. Everything that unfolds in history and creation is under the sovereign governance of Christ, who actively engages with and directs these events to fulfill His divine purpose.
