John Nelson Darby emphasizes the eternal sonship of Christ, arguing that the term 'Son' refers to the Person of Jesus rather than His nature. He warns against confusion regarding the Trinity and asserts that the Son existed before creation, actively participating in God's works. Darby highlights that understanding Jesus as the Son is crucial for recognizing His divine authority and the relationship between the Father, Son, and Holy Spirit. He stresses the importance of Scripture in affirming this truth and cautions against human interpretations that undermine the glory of Christ's sonship. Ultimately, he calls for a deeper appreciation of the Son's role in creation and redemption as foundational to Christian faith.
