Old Covenant Signs in Redemptive History

Over at Ligonier, I recently contributed a short series on the Old Covenant signs. When each of the Old Covenant signs (i.e., the rainbow, Sabbath, circumcision, and the Passover) are viewed in light of the fulfillment of all that they typified, we come to understand a great deal about the work of Christ. Here are the four installments in this series on the Old Covenant signs in redemptive history: 

The Rainbow as a Sign of the Covenant

The Sabbath as a Sign of the Covenant 

Circumcision as a Sign of the Covenant 

The Passover as a Sign of the Covenant
