How do we know Christ's rule is established?

The New Testament affirms that Jesus Christ, born of the woman, is destined to rule all nations with a rod of iron. As seen in Revelation 12:5, the child is caught up to God, signifying His exaltation and authority. This is echoed in Psalm 2 where God declares that He has set His king upon His holy hill, emphasizing the sovereignty of Christ. His rule is not merely a future promise but is currently established as He reigns from the right hand of the Father, making all things subject to Him. This gives believers confidence in His ultimate victory over sin and death.
