How do we know the doctrine of Christ's sovereignty is true?

The sovereignty of Christ is a doctrinal cornerstone rooted deeply within the biblical narrative. In Psalm 75, we see that 'promotion cometh neither from the east nor the west nor from the south, but God is the judge' (Psalm 75:7). This indicates Christ's supreme authority over all creation, underscoring His ability to raise up and bring down. Furthermore, New Testament references such as Ephesians 1:22 and Philippians 2:9-11 affirm Christ's exaltation and authority over all things. His reign is established not only in the past through His resurrection and ascension but continues in the present as He actively governs all aspects of creation for the good of His chosen people.
