Why is the doctrine of the eternal sonship of Christ important for Christians?

The doctrine of the eternal sonship of Christ is crucial for understanding His divine nature and redemptive work. This doctrine asserts that Jesus is not merely a created being but has eternally existed as the Son of God. As highlighted in John 1:1, 'In the beginning was the Word, and the Word was with God, and the Word was God,' affirming Christ's co-eternity with the Father. This belief positions Jesus as fully God and fully man, essential for the authentic nature of the salvation He provides. The Apostle John emphasizes this truth repeatedly, as it is foundational for maintaining true faith and understanding one's relationship with God. Any deviation from this doctrine leads to a misunderstanding of who Christ is and ultimately undermines the entirety of the Gospel message.
