Opening Meditation: As we approach the profound truth of God's holiness, let us pause to reflect on the weightiness of this divine attribute. The seraphim proclaim, "Holy, holy, holy is the Lord of hosts," beckoning us to recognize not only God's majesty but also our own unworthiness in light of His perfection. 1. Definitive Truth: God's holiness is the foundation of His character. It is the essence of His being, defining Him as supremely separate from all sin and imperfection. Unlike any other attribute, His holiness is proclaimed thrice in Isaiah 6:3, emphasizing its preeminence. This repetition serves as a threefold proclamation of the weightiest attribute of God, underscoring that holiness is not merely a part of God’s nature but His very essence—who He is! 2. Micro-Teaching: In classical theism, God’s attributes are understood through the lens of divine simplicity, meaning they are not separate parts of God but rather unified expressions of His singular nature. Holiness, as an infinite quality, reflects God’s transcendence, moral purity, and perfection. When Isaiah encounters God’s holiness, he recognizes his sinfulness, stating, “Woe is me! For I am lost.” This reaction illustrates how God’s holiness acts as a mirror, revealing the depth of human depravity. Jonathan Edwards posited that this very attribute can lead sinners to despise God, for they see in Him the stark contrast to their sinfulness. 3. Theological Note: The law of God, as a reflection of His holiness, serves to illuminate our moral failures. It is through this divine standard—the Ten Commandments, a summary of God’s moral law and holy character—that we recognize our sinfulness and our desperate need for Christ as Savior. Reformed Theology emphasizes that God’s holiness is the basis for His justice (Exodus 34:6-7), and it is only through Christ's atoning work that we can be reconciled to this holy God (2 Corinthians 5:18-19). The principles of Christian metaphysics further affirm that God's character and essence are intertwined, leading us to understand that His attributes of love, mercy, and grace are rooted in His perfect holiness. So when God loves, it is a holy love; when God shows mercy and grace, it is a holy mercy and grace that necessarily leads to holiness.
