How do we know that Christ is preeminent over all creation?

The title 'firstborn' in Colossians 1:15 indicates Christ's rank, authority, and His role as the inheritor of all creation. Verse 16 elaborates that by Him all things were created, and all things consist through His will. This emphasizes that everything in both heaven and earth—thrones, dominions, principalities, and powers—was created by Him and for Him. Therefore, as the firstborn, He not only has authority over creation but also ensures that creation fulfills its purpose in connection to Him. This establishes His absolute preeminence over all things.
