Is the God of the Old Testament different from the God of the New Testament?
The God of the Old and New Testaments is one, unchanging in nature, but His expression shifts according to humanity’s developmental stage. The Old Testament emphasized justice for humanity in a "formation stage." The New Testament, through Jesus, revealed God's love and grace, suitable for humanity in a "growth stage." These reflect God's progressive providence to restore fallen humanity to His original ideal, moving from external law to an internal heart.
The question of whether the God of the Old Testament differs from the God of the New Testament is foundational to understanding God’s character and consistent plan for humanity. While biblical narratives present seemingly contrasting portrayals, the Divine Principle clarifies that this does not indicate a change in God’s nature, but rather a progressive providence of restoration tailored to humanity’s spiritual capacity.
The Biblical Foundation: God's Varied Expressions
The Bible undeniably presents what appear to be contrasting expressions of God. In the Old Testament, God is frequently depicted as a God of strict justice and judgment, demanding obedience and punishing transgression. For instance, God proclaims, “You shall have no other gods before me” (Exodus 20:3). The principle of retributive justice is evident: “If anyone injures his acquaintance, as he has done so it shall be done to him: fracture for fracture, eye for eye, tooth for tooth; just as he has injured a man, so it shall be inflicted on him” (Leviticus 24:19-20). The flood narrative illustrates God’s wrath against sin: “The Lord saw that the wickedness of man was great in the earth... And the Lord said, ‘I will blot out man whom I have created from the face of the land’” (Genesis 6:5, 7). This paints a picture of a potent and righteous God.
Conversely, the New Testament emphasizes a God of unconditional love, grace, and forgiveness, epitomized in Jesus Christ. Jesus teaches, “But I say to you, love your enemies and pray for those who persecute you” (Matthew 5:44), elevating the standard beyond retribution. John declares, “Anyone who does not love does not know God, because God is love” (1 John 4:8) and “God is love, and whoever abides in love abides in God, and God in him” (1 John 4:16). God’s ultimate redemptive love is expressed: “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life” (John 3:16). These apparent differences can lead to confusion if God's unchanging nature is not understood.
Divine Principle's Clarification: God's Unchanging Nature and Progressive Providence
The Divine Principle asserts that God’s fundamental nature is absolute, eternal, and unchanging. Scripture confirms this: “For I the Lord do not change” (Malachi 3:6) and “Every good gift and every perfect gift is from above, coming down from the Father of lights with whom there is no variation or shadow due to change” (James 1:17). The apparent variations reflect God's progressive providence of restoration, adapted to humanity’s spiritual state and capacity to receive His truth. This progression aligns with the three stages of growth: formation, growth, and completion.
The Old Testament corresponds to the formation stage of God's providence, similar to the dove in Abraham's offering, representing the earliest stage of spiritual development. During this era, humanity, deeply fallen, required external law and commandments to establish a foundation of faith. The "eye for an eye" principle, while strict, was a necessary step to limit vengeance and instill basic justice. The people were justified by their works, following the Law, and became form spirits in the spirit world. This stage served to lay a foundation for resurrection.
The New Testament, through Jesus, represents the growth stage of God's providence, symbolized by the ram. Through Jesus, God revealed His internal heart of love and grace, as humanity's spiritual foundation had sufficiently developed. Jesus came to fulfill, not abolish, the law, elevating it from external obedience to internal, heart-centered love (Matthew 5:17). In this age, people could achieve righteousness through faith in Jesus and the Gospel, becoming life spirits. Jesus also brought a brighter light, symbolically causing Moses (sun) and the Law (moon) to lose their light, and the children of Israel (stars) to fall when they rejected him. The current era of the Last Days, the end of the New Testament era, is preparing for a new and even brighter light from the Lord of the Second Advent.
Understanding the Deeper Meaning: God's Dual Characteristics
God inherently possesses dual characteristics of internal character (internal character/Heart) and external form (external form/Logos/Law), manifesting as love and justice. These are complementary. In the Old Testament, due to humanity's profound fallenness, God’s external form, or justice, was predominantly expressed to establish external conditions for restoration and train humanity in obedience. This period required humanity to pay indemnity conditions to curb sin and begin separating from Satan. The various conditions of indemnity, such as a conditional object and a period of time, were set to restore what Adam and Eve lost. The law and the temple served as conditional objects in the Old Testament age.
With the New Testament, through Jesus, God revealed His internal character—His boundless love and grace—His ultimate desire. Jesus taught the internal spirit of the law, focusing on spiritual transformation, offering the gospel and sacraments as conditional objects for faith. This shift was not a change in God's character but in humanity's readiness to perceive and respond to His full, internal being. The subsequent age, the Completed Testament Age, is symbolized by the heifer, representing the completion stage, the age of the bride after the Second Advent, leading to the Kingdom of Heaven on Earth.
Living the Principle
Understanding God's consistent nature across both Testaments empowers us to live a more balanced and purposeful life, reflecting His true character.
1. Embrace God as a loving, developmental Parent; His providential adaptations guide humanity toward ultimate growth. 2. Harmonize love and justice in your relationships, recognizing that true love includes guiding principles and accountability. 3. Actively seek and receive the "new light" and truth that God provides in each era, understanding that previous revelations, while valuable, may lose their central illuminating power in comparison. 4. Strive for spiritual growth from form spirit, through life spirit, to divine spirit, participating fully in God's ongoing providence of resurrection and restoration.
