Why is the eternal work of Christ important for Christians?

Understanding the eternal work of Christ is essential for Christians as it directly impacts our salvation and daily lives. The work of Christ—His life, death, and resurrection—has not only redeemed us from sin but has also given us a new nature, allowing us to live in a manner pleasing to God. In 1 Peter 1:22-25, we see that believers are called to purify their souls by obeying the truth through the Spirit, which leads to a genuine love for one another. This transformation is only possible because of the work of Christ that abolishes old covenant requirements and establishes a new covenant based on grace. Furthermore, as Romans 8:30 explains, those whom He called, He also justified and glorified, ensuring we can trust in His ongoing work in our lives as we await His return.
