Why do Christians need to read the Old Testament?

For Christians, engaging with the Old Testament is essential as it forms the foundation of our understanding of Christ and the entirety of Scripture. The Old Testament points to the coming of Christ and is filled with types and shadows that reveal His nature and purposes. As stated in Romans 15:4, 'For whatever was written in former days was written for our instruction, that through endurance and the encouragement of the Scriptures we might have hope.' By studying the Old Testament, believers grow in their knowledge of God’s faithfulness and His plans throughout history, ultimately leading to a deeper appreciation of the New Testament's fulfillment in Christ. Thus, it enriches our faith and deepens our relationship with God.
