We must proceed from the first principles of the doctrine of Christ unto perfection, and not lay the foundation a second time, Heb 6:1-3. Those who were once enlightened, and have been made partakers of the Holy Ghost and the various blessings of the Gospel, if they apostatize from Christ, and finally reject him as their Savior, cannot be renewed again to repentance, Heb 6:4-6. The double similitude of the ground blessed of God, and bearing fruit; and of that ground which is cursed of God, and bears briers and thorns, Heb 6:7, Heb 6:8. The apostle's confidence in them, and his exhortation to diligence and perseverance, Heb 6:9-12. God's promise and oath to Abraham, by which the immutability of his counsel is shown, in order to excite our hope, Heb 6:13-18. Hope is the anchor of the soul, and enters within the veil, Heb 6:19, Heb 6:20.
