The Old and New Covenants: A Study in Transformation and Fulfillment

The Bible is divided into the Old Testament and the New Testament, not merely as a chronological distinction but as a representation of how God's redemptive plan has evolved and been fulfilled. The Old Covenant, established through Moses, centers on the laws and rituals of the time, while the New Covenant, given through Jesus Christ, emphasizes spiritual renewal and the indwelling of the Holy Spirit. Together, they reveal different expressions of God’s love and the path to human salvation.

1. The Old Covenant: The Covenant at Mount Sinai

1.1 The Nature of the Old Covenant

• Origin:
  The Old Covenant began when God gave Moses the Ten Commandments and the law.

• Form:
  Written on stone tablets, the covenant outlined the terms of the relationship between God and His people.

• Content:

  • Love for God:
    Demonstrated through observing festivals and sacrifices that brought the people closer to Him (e.g., Passover, Sabbath, Day of Atonement).
  • Love for Neighbor:
    Emphasized through the latter commandments (5th–10th), which governed interpersonal relationships.

1.2 Challenges of the Old Covenant

• The Israelites often failed to uphold the covenant, breaking their relationship with God.
• Jeremiah 31:33 prophesied a new covenant:

  “I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.”

• This new covenant would move beyond external observance, placing the law within the hearts of God’s people.

2. The New Covenant: Written by the Spirit

2.1 Core of the New Covenant

• Inauguration:
  The New Covenant was established through Jesus' sacrifice on the cross.

• Form:
  The law is now inscribed on the hearts of believers through the Holy Spirit.

• Content:
  While retaining the essence of loving God and neighbor, the New Covenant emphasizes inner transformation and spiritual purity.

2.2 The Sermon on the Mount: The New Covenant Explained

• Jesus’ teachings in the Sermon on the Mount (Matthew 5–7) transcend the Old Covenant by focusing on the heart’s intentions.

  • Murder and Hatred:
    • Old Covenant: “Do not murder.”
    • New Covenant: “Hatred in your heart is equivalent to murder.”
  • Adultery and Lust:
    • Old Covenant: “Do not commit adultery.”
    • New Covenant: “Lustful thoughts are akin to adultery.”

• Conclusion:
  The New Covenant condemns sin at its root—the heart—rather than merely regulating outward actions.
  Matthew 5:8:

  “Blessed are the pure in heart, for they will see God.”

4. Passover and the New Covenant: Truth vs. Misinterpretation

4.1 The Passover and the New Covenant

• Passover:
  An Old Testament festival commemorating Israel’s deliverance from Egypt through the blood of the lamb.
• New Covenant:
  Jesus fulfilled the Passover and all other laws through His sacrifice, bringing complete salvation.

4.2 Misinterpretations by the World Mission Society Church of God

• They claim the Passover is central to the New Covenant, equating it with salvation.
• The Truth:
  The New Covenant is not about adhering to rituals like the Passover but about heart transformation and Jesus’ redemptive work.
  • The Passover points to Christ, the ultimate sacrificial Lamb, who completed the law and established a new way of worship.

5. Conclusion: The New Covenant is the Law of the Heart

5.1 Fundamental Differences Between the Covenants

• Old Covenant:
  Focused on external actions, rituals, and a temple-centric faith system.
• New Covenant:
  Centers on internal transformation, emphasizing the Holy Spirit’s guidance, with each believer as God’s temple.

5.2 The Essence of the New Covenant

• The New Covenant goes beyond rituals or external festivals.
• It calls for renewal through Jesus’ teachings, enabling believers to love and serve God and others wholeheartedly.

Biblical Insight

Hebrews 10:18:

“And where these have been forgiven, sacrifice for sin is no longer necessary.”

• Jesus’ sacrifice completed the New Covenant, shifting the focus from external deeds to internal renewal and offering true freedom and salvation.

Final Thoughts

The distinction between the Old and New Covenants lies not only in form and content but also in the essence and direction of faith. As Christians, understanding and living out the principles of the New Covenant—guided by the Holy Spirit and centered on Christ’s redemptive work—is essential. Let us embrace this transformation, practicing a faith rooted in love, grace, and heartfelt obedience to God’s will.
