Why is Jesus' sovereignty important for Christians?

The sovereignty of Jesus Christ is fundamental to the Christian faith as it underpins the assurance of our salvation. He has been given authority over all flesh (John 17:2), which establishes that He governs not only the universe but also the outcomes of His redemptive work. When we recognize His sovereignty, we find comfort knowing that our salvation does not depend on our actions but solely on His grace and power. This is reinforced by the belief that our Savior's success in His mission guarantees that all whom the Father has given to Him will be preserved and ultimately brought to glory, as indicated in Philippians 1:6, which states that He who began a good work in us will carry it on to completion.
