How do we know Jesus as the eternal Son of God is true?

The concept of Jesus as the eternal Son of God is confirmed through biblical passages that denote His divine sonship and co-equality with the Father. For instance, Micah 5:2 not only speaks to Christ's earthly origin but also to His eternal existence. The New Testament reinforces this by describing Him as the 'Only Begotten' of the Father (John 1:14). Furthermore, the eternal sonship is seen as the foundation of His sacrificial role, as it qualifies Him to represent humanity before divine justice. The Reformed tradition emphasizes that understanding Christ's sonship is crucial for grasping the Gospel's essence, as it correlates to salvation.
