Isaiah 9:6-7 prophesies Jesus Christ of Nazareth, the promised Son of God, and gives Him the title Everlasting Father. Though He came to reveal the Father (Luke 10:22; John 1:18), the title makes sense once one recognizes who the God of the Old Testament is. Scripture shows that Christ created all things (John 1:3; Colossians 1:16; Hebrews 2:10), and I Corinthians 10:4 identifies the Rock of the Old Testament as Christ. The One called Yahweh is therefore Jesus Christ, Savior and King. Deuteronomy 32:6 shows this God claiming fatherhood over Israel on three bases: He redeemed them from slavery in Egypt, created them, and founded them as a nation. He has every right to the title. In Jeremiah 31:9, He says He is a Father to Israel and that Ephraim is His firstborn, speaking of the future time when Israel repents. This shows He will be their Father when He returns to establish His world-ruling government, and that this special relationship will last throughout eternity. He is indeed the Everlasting Father.

Jesus Christ is identified as The Rock, a symbol of immense power and steadfastness, reflecting His role as a foundational figure in both the Old and New Testaments. In Deuteronomy 32:18, He is portrayed as the Rock who begot Israel, reminding us of His role as Creator and Father to the Israelites. This imagery underscores His complete involvement in their creation, acting as both Father and Mother, with no collaborator or foreign god aiding Him in the process. As the Rock from which they were hewn, as mentioned in Isaiah 51:1, He is the ultimate source of their origin, beyond even Abraham, emphasizing His foundational role in their existence. Furthermore, in I Corinthians 10:1-4, the Apostle Paul draws on the imagery of the Spiritual Rock that followed Israel through the wilderness, explicitly stating that this Rock was Christ, the same God of the Old Testament who supplied them with sustenance and led them to the promised land. This continuity highlights that Jesus Christ, as The Rock, remains the same yesterday, today, and forever, embodying the same character and power across time.
