I Am with You, Declares the Lord (Haggai 1:13)

Haggai 1:13 says, "Then Haggai, the Lord’s messenger, gave this message of the Lord to the people: ‘I am with you,’ declares the Lord." This reassurance was given to the Israelites who had returned from exile and were tasked with rebuilding the temple. They were discouraged and overwhelmed by the enormity of the task, but God, through Haggai, reminded them that He was with them, providing the strength and encouragement they needed to continue their work. Today, this verse is a powerful reminder that God’s presence is always with us, especially when we face daunting challenges. Just as the Israelites felt overwhelmed by the task of rebuilding, we too often encounter situations that seem beyond our abilities. Whether it is a demanding job, family responsibilities, or personal struggles, we can feel discouraged and unsure of how to move forward. In these moments, God’s declaration, "I am with you," offers us the comfort and strength we need to persevere. Making this re

How do the Old Testament and New Testament Relate to One Another?

An understanding of how the Old Testament and the New Testament relate to each other is essential to understand the Bible in its entirety and God’s plan for humanity. 

The Bible is a two-part collection of religious texts, separated into the Old Testament, primarily outlining history, laws, and prophecies, and the New Testament, focusing on the life, teachings, death, and resurrection of Jesus Christ. 

But how do these two significant parts of the Bible relate? Do they oppose each other, or are they parts of a harmonious whole? Let us dive into the details.

Continuity and Fulfillment

One fundamental aspect of the relationship between the Old and New Testaments is the concept of continuity and fulfillment. 

The prophecies of the Old Testament were fulfilled in the New Testament, specifically in the person of Jesus Christ. 

For example, Isaiah 53, a well-known Old Testament prophecy, is the prediction of Christ's suffering and death. The Gospel of Matthew frequently mentions how Jesus' life events "fulfilled what was spoken through the prophet."

The Same God

The Old Testament and the New Testament relate to each other by depicting the same God. The God who created the world in the Old Testament is the same God who, in the New Testament, sent Jesus Christ as the Savior of the world. 

The nature of God, His attributes of love, justice, mercy, and holiness are displayed in both Testaments.

Covenantal Relationship

The covenants found in the Old Testament point forward to the New Testament. In the Old Testament, God establishes several covenants with individuals like Noah, Abraham, and Moses and with the nation of Israel. 

These covenants, agreements with specific stipulations and promises, point forward to the New Covenant. 

This New Covenant, introduced by Jesus at the Last Supper (Luke 22:20), promises forgiveness of sins and a transformed heart through faith in Christ. 

Thus, the Old Testament covenants are seen as precursors to the ultimate New Covenant.

Law and Grace

The relation between law in the Old Testament and grace in the New Testament is another area of interaction. 

The law given to Moses outlined how people should live. However, due to human imperfection, no one could fully adhere to the law. 

In the New Testament, grace, as exhibited in the life and death of Jesus, is seen as the answer to this problem. 

Jesus fulfilled the law's requirements perfectly, and through faith in Him, individuals can have a right relationship with God. This does not mean that the law is irrelevant, but it places it in the context of grace and faith.

The Promise of the Messiah

The Old Testament and the New Testament relate to each other through prophecies. The Old Testament contains numerous messianic prophecies that are fulfilled in the New Testament through Jesus. 

These prophecies foretell various aspects of birth, life, death, and resurrection. 

The writers of the New Testament link Jesus to these prophecies to validate His identity as the Messiah, demonstrating a crucial relation between the two Testaments.

Ethical Consistency

The laws of the Old Testament and wisdom literature provide ethical guidelines that continue to be relevant in the New Testament. 

Concepts like love, justice, and care for the poor are emphasized in both sections of the Bible. Jesus, in the Sermon on the Mount, deepens and intensifies many of these ethical teachings.

The Story of Salvation

The Old Testament and the New Testament collectively tell a grand story of creation, fall, redemption, and restoration. 

The Old Testament sets the stage, depicts humanity’s problem of sin, and anticipates a solution. The New Testament presents the resolution through Jesus Christ's life, death, and resurrection, offering redemption and anticipating a future restoration. 

Therefore, the New Testament is a continuation and climax of the narrative arc started in the Old Testament.

Continuation of Faith Traditions

The New Testament church did not abandon all Jewish customs and rituals; many of these traditions carried forward into the life of the early Christian church. 

The act of communion, for example, was rooted in the Jewish Passover meal, as was the practice of reading and interpreting Scripture in the community.

Theological Themes

The same foundational theological themes are presented in both the Old Testament and the New Testament, including but not limited to the sovereignty of God, human sinfulness, the need for redemption, and the ultimate hope of a restored world. 

These themes provide a strong thread of continuity and relationship between the two.


While there are differences in context, culture, and emphasis between the Old Testament and New Testament, they are integrally connected parts of a cohesive whole. The Old Testament is not obsolete but remains fundamental to the Christian faith. 

It provides the backstory, prophecies, and the framework of understanding that make the events of the New Testament significant. 

The New Testament, on the other hand, is not a completely new story but rather a fulfillment and continuation of the Old Testament. 

It provides an answer to humanity's problems outlined in the Old Testament, offers the completion of the Old Testament prophecies, and projects the culmination of God's plan for humanity. 

Understanding the relationship between the Old Testament and the New Testament enhances one's comprehension of the Bible as a whole. 

Instead of viewing them as separate entities, it is more beneficial to see them as a unified narrative, each illuminating the other and together providing a complete picture of God’s interactions with humanity.
