Did Jesus come to replace the Old Testament—or fulfill it?

In this sermon from RPM, Pastor Jeremiah Dennis unpacks Matthew 5:17 to show why Christians must not “unhitch” from the Old Testament and how Christ perfectly fulfills the Law and the Prophets in at least five powerful ways.

You’ll discover:
Why the “angry OT God vs. kind NT God” idea is wrong
How Jesus confronts man‑made religion but honors God’s Law
Five specific ways Christ fulfills the Old Testament
Why your righteousness will never be enough—and why that’s good news
How the Spirit empowers believers to actually live out God’s Law
