WHEN I SEE THE BLOOD (Dam)

BIG IDEA:

The blood of the lamb is GOD’s appointed sign of substitution and protection; redemption by blood creates a remembering, holy, covenant people — and the power of the blood never diminishes.

INTRODUCTION

Exodus 12 is the theological summit of the Exodus narrative.

The plagues culminate.

Judgment is imminent.

Death is coming.

And then GOD declares:

“And the blood shall be to you for a sign upon the houses where ye are: and when I see the blood, I will pass over you…” (Exodus 12:13)

That verse is the hinge of redemption.

Everything turns on the blood.

• Not effort.

• Not emotion.

• Not heritage.

When I see the blood.

I. THE BLOOD AS THE SIGN (12:13)

13 Now the blood shall be a sign for you on the houses where you are. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt.

The Hebrew word for “sign” is ???? (’oth) — a visible covenant mark recognized by GOD.

It was: Objective, External, Public, Decisive/Critical

The blood on the door declared:

• A death has already occurred here.

• Judgment has already fallen here.

• Justice has already been satisfied here.

The blood did not remind GOD to be merciful.

It satisfied GOD’s justice.

Inside those homes may have been trembling parents and crying children.

But if the blood was on the door - they were safe.

Because security did not rest in their calmness.

It rested in the covenant sign.

This anticipates the Gospel:

“Being now justified by his blood…” Romans 5:9

Romans 5:9 Much more then, having now been justified by His blood, we shall be saved from wrath through Him.

And:

“For even Christ our Passover is sacrificed for us.” 1 Corinthians 5:7

• 1 Corinthians 5:7 Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover, was sacrificed for us.

The blood never needed reinforcement.

It was sufficient the moment it was applied.

And remember church; THE BLOOD NEVER LOSES ITS POWER.

The blood that covered that doorpost protected that house fully.

The blood of CHRIST fully satisfies divine justice.

• Not partially.

• Not temporarily.

• Not emotionally.

…FULLY.

II. REDEMPTION MUST BE REMEMBERED (12:14)

14 14 ‘So this day shall be to you a memorial; and you shall keep it as a feast to the LORD throughout your generations. You shall keep it as a feast by an everlasting ordinance.

A Perpetual Ordinance

“This day shall be unto you for a memorial…”

Passover was not a one-time event.

It was to be remembered throughout generations.

Redemption must be remembered.

GOD commands them to rehearse deliverance.

Why?

Because people forget grace.

Because forgetfulness leads to spiritual drift.

Redemption must be rehearsed.

Israel would celebrate Passover annually to remember:

• The night of judgment

• The mercy of GOD

• The power of the blood

Likewise, the LORD’s Supper (instituted in the Gospel of Luke 22) keeps the church remembering.

• Luke 22:14-20 Institution of the LORD’s Supper

Luke 22:19-20 19 And He took bread, gave thanks and broke it, and gave it to them, saying, “This is My body which is given for you; do this in remembrance of Me.”

20 Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you.

• 1 Corinthians 11:24-26 24 and when he had given thanks, he broke it, and said, “This is my body, which is for you. Do this in remembrance of me.” 25 In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” 26 For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.

We do not reapply the blood.

We remember the blood already applied.

Because the blood never loses its power.

III. REDEMPTION PRODUCES HOLINESS (12:15–20)

The Removal of Leaven

15-20 15 Seven days you shall eat unleavened bread. On the first day you shall remove leaven from your houses. For whoever eats leavened bread from the first day until the seventh day, that person shall be cut off from Israel. 16 On the first day there shall be a holy convocation, and on the seventh day there shall be a holy convocation for you. No manner of work shall be done on them; but that which everyone must eat—that only may be prepared by you. 17 So you shall observe the Feast of Unleavened Bread, for on this same day I will have brought your armies out of the land of Egypt. Therefore you shall observe this day throughout your generations as an everlasting ordinance. 18 In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, until the twenty-first day of the month at evening. 19 For seven days no leaven shall be found in your houses, since whoever eats what is leavened, that same person shall be cut off from the congregation of Israel, whether he is a stranger or a native of the land. 20 You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread.’ ”
