Redeemer Equips: OT Survey II

Session 2: From Sinai to the New Covenant

The Theme: The Law, the Kingdom, and the Hope of a New Heart

I. The Mosaic Covenant: Law and Types (20 Minutes)

The Context: Exodus 19–24. The Tabernacle and the Law.

The Purpose: The Law does not replace the promise to Abraham; it serves it (Gal 3).

The Threefold Use of the Law:

Pedagogical: To show us our sin and lead us to Christ.

Civil: To restrain evil in society.

Normative: To guide the believer in thankful living (the "Third Use").

Ceremonial Law: How the sacrifices and the Tabernacle act as "types" and shadows pointing to the ultimate sacrifice of Jesus.

II. The Davidic Covenant: The Eternal Kingdom (15 Minutes)

The Context: 2 Samuel 7.

The Promise: A descendant of David will sit on the throne forever.

The Connection: This narrows the "seed" of the woman (Adam) and the "seed" of Abraham down to a specific royal line.

Reformed Insight: Christ is the true King. The failures of the earthly kings of Judah serve to increase the longing for the "Greater David."

III. The Prophets and the "New Covenant" (15 Minutes)

The Context: Jeremiah 31 and Ezekiel 36.

The Tension: Israel has broken the Mosaic covenant. They are in exile.

The Solution: God promises a New Covenant where the Law is written on the heart, sins are remembered no more, and the Holy Spirit is given.

Continuity: This is not a "Plan B," but the fulfillment and "climax" of the Covenant of Grace.

IV. Conclusion: The One Story (10 Minutes)

Summary: The Old Testament is a story of God’s relentless faithfulness to His covenant promises.

The Link to Christ: Briefly show how Jesus is the:

True Adam (Success where Adam failed).

True Israel (Kept the Law perfectly).

True David (The Eternal King).

Application: We enter this covenant not by our works, but by being "in Christ" through faith.
