The sermon centers on the title 'Everlasting Father' ascribed to Christ in Isaiah 9, emphasizing His eternal nature and divine role as the source and sustainer of all creation, salvation, and the church. It underscores that Christ, though incarnate as a child, is eternally existent—without beginning or end—revealing God's timeless character through Scripture, from the eternal throne of Psalm 45 to the eternal salvation described in Hebrews and John. The preacher highlights Christ as the Father of all believers, the author of eternal life, and the eternal guardian of His church, which will endure forever despite earthly trials and false teachings. The message calls listeners to a decisive spiritual choice: to recognize Christ as the Father of one's eternal destiny or remain under the dominion of the devil, with no middle ground, urging repentance and faith in light of eternity's reality.
