Why is it said that Christ is all in all?

In Colossians 3:11, we are told that Christ is all, and in all, which signifies His preeminence and centrality in every aspect of a believer's existence. This truth emphasizes that all spiritual realities, hope, salvation, and fellowship arise from Christ. He is not only the means of our salvation but the ongoing source of our strength, peace, and purpose. Acknowledging that Christ is all in all shapes the way believers view themselves and others, reminding us that nothing of human merit can stand before His glory, ultimately uniting us in the body of Christ irrespective of our backgrounds.
