Prelude

The Foundations of the Encounter with God

“And they shall know that I am the LORD their God, who brought them out of the land of Egypt, that I might dwell among them. I am the LORD their God.”
Exodus 29:46

Goal of the Prelude: By the end of this lesson, you will understand that the system of worship in Leviticus is not an instruction manual written in a foreign language, but a divinely designed map. Together, we will decipher its code, understanding that before any ritual, God established, by pure grace, three indispensable pillars or “master keys”: the Covenant that creates a relationship, the Sacred Place for encounter, and the Priesthood that serves as a bridge.

Before Entering the Sanctuary

Have you ever opened the Bible to Leviticus and felt as if you were reading the instruction manual for a device no one makes anymore? Sacrifices, rituals, animals, blood. Rules about what is pure and impure that sound as if they belong to another planet. It is easy to close the book with the feeling that it has nothing to say to you.

But what if I told you that this book, which almost no one finishes reading, is actually one of the most precise and surprising maps God ever drew for meeting with His people? Not a list of demands. A map toward joy.

What we are going to do together is decipher that code. Because Leviticus is not a chaos of rules: it is a system designed with a coherence that, once you see it, you cannot unsee. Every piece fits. Every rite has a purpose. And that purpose is not to drive you away from God with impossible demands, but to lead you to enjoy His nearness. Think of it as a divine GPS, but one that not only tells you where to go, but has already placed you on the road.

Before entering the sanctuary, there is one thing you need to understand, and it changes everything else: grace always comes before ritual. Always. Without exception.

Leviticus was not given to slaves who were still trying to become free. It was given to a people who had already crossed the Red Sea, had already seen the waters divide, had already eaten manna in the wilderness. God first brought them out. Then He gave them the instructions. That is not a minor detail: it is the key for reading the whole book.

Leviticus is not the manual for earning God. It is the manual for caring for something God had already given. There is a vast difference between those two things. The first produces a false religion. The second produces a true relationship. And we are going to read this entire book with that difference in mind.

Before even speaking of the offerings or climbing the “ladder of worship,” we need to hold in our hands three master keys, three requirements that were not negotiable for opening the door to enjoyment in the sanctuary.

1. The First Key: The Covenant That Creates a People

The first key is the Covenant. And to understand it, we must go to Sinai, to the most decisive moment in Israel’s history. Cloud, fire, thunder, and Moses ascending to speak with the God of the universe. There, in Exodus 24, God did not dictate a regulation. He sealed an alliance. One with blood, with witnesses, with a promise that forever changed what Israel was.

That blood sprinkled on the altar and on the people was not a transaction of payments. It was the language of family. It was God saying: “Now we are united.” A group of slaves without history or identity had just become the people of the God of the universe. Not because they deserved it. But because He wanted it.

Without this prior covenant, Leviticus would simply be a list of arbitrary rules imposed by a demanding god. But within the covenant, every rite is a way of caring for something precious: the relationship God initiated by His own initiative. The covenant is the ground. Everything else grows upon it.

Worship is not born from the human effort to reach a distant god. It is born from the response to a God who has already drawn near.

The covenant is the guarantee that the enjoyment of communion is possible, not because the people are perfect, but because God has committed Himself to them. It is divine initiative that opens the door. Therefore, when the people accept at the foot of Sinai, saying, “All that the LORD has spoken we will do, and we will obey” (Exodus 24:7), they are not signing in order to earn the relationship; rather, they are accepting the terms for living within the relationship that God, by grace, has just given them.

2. The Second Key: A Place for the Encounter

The relationship was sealed. But a relationship needs a place where it can happen. It cannot be anywhere, in any way, at any time. God knew this. That is why He designed something extraordinary: a physical space, built according to His own instructions, where He promised to dwell.

Once the relationship had been established through the covenant, a second key was needed: a Place of Encounter. Worship was not going to be something that happened anywhere and in any manner. It was going to be a sacred encounter in a space and under conditions that God Himself had placed on the table.

That place was the Tabernacle. Not a field chapel. Not a meeting tent. It was the space where the God who created the heavens and the earth said: “Here I live. In your midst.” That alone should leave us speechless.

It was not simply a tent for rituals; it was the tangible manifestation of God’s promise to dwell among His people. “And I will set my tabernacle among you, and my soul shall not abhor you” (Leviticus 26:11). Every detail of the Tabernacle was a language. The fabrics, the metals, the colors, the arrangement of the furniture: everything communicated something about who God was and how one could joyfully come to Him. It was not decoration. It was theology made space.

The central Place of Encounter of everything was, in reality, three places: the Bronze Altar, the Golden Altar, and the Mercy Seat, which was the cover of the Ark of the Covenant in the Most Holy Place.[1]

At the heart of it all was the Mercy Seat: the cover of the ark, in the Most Holy Place. There, between the cherubim, God promised to speak. Not from far away. Not from an abstract heaven. From that specific point, in that specific tent, in the midst of His specific people. “There I will meet with you” (Exodus 25:22). The boldest intimacy imaginable.

God Himself promised it: “And there I will meet with you, and I will speak with you from above the Mercy Seat...” (Exodus 25:22). The Tabernacle, therefore, was not a place for keeping God at a distance, but the divinely designed space for making possible and safe the joyful encounter between God and His people.

3. The Third Key: A Bridge Between God and Man

The covenant created the relationship. The Tabernacle created the space. But one question remained unanswered: how can an imperfect people enter the presence of a perfectly holy God without being destroyed by it? For that, there was the third key: the Priesthood.

The Place of Encounter required ritual maintenance: the cleansing of the spaces appointed by God for meeting with His people — the Bronze Altar, the Golden Altar, and the Mercy Seat — a cleansing carried out by means of the blood of an offering for the purification of those places, the ḥaṭṭā’t. Therefore, God instituted the priests — Aaron and his sons, with the Levites added to their service — as consecrated ministers whose first responsibility was to bear responsibility for the sanctuary and maintain its cleanliness against the contamination produced by the non-intentional faults of the people (cf. Num 18:1–7; 5:1–4; Lev 5–6; 16:16–19), performing the purifications. On that basis, in the previously purified Places of Encounter, they presented the offerings of the people before God.

The priests were not guards who prevented access. They were the ones who made it possible. They kept the way clean, administered the offerings, and taught the people to distinguish the holy from the common. Without them, the encounter had no channel. With them, any Israelite could draw near.

But there was a limit. Involuntary faults, errors, the impurities of daily life: for these there were offerings. For deliberate betrayals, sins committed with open eyes and a hardened heart, the system remained silent — the “high-handed” sin, which involved breaking any of the Ten Commandments.[2] There was no rite. Only sentence.

That limit was not a defect in the design: it was a warning that something greater would come afterward (cf. Num 15:30–31), with no provision of ḥaṭṭā’t, the offering for the purification of the contamination caused by sin. Thus, the priesthood does not compete with the Covenant or with the Place of Encounter, but serves them: under the Covenant, it guards the terms of the relationship; in the Place, it guarantees that the movement toward the presence takes place according to the standards of divine purity. In the ladder of worship, the priesthood acts as the cleaning and maintenance staff of the steps, facilitating free passage for the people of the Covenant.

The priests were the administrators of the sanctuary. They taught. They mediated. They kept the way open. And none of them chose that role: God appointed them. No one applies to be the bridge between the human and the divine. That can only be received.

As the author of the letter to the Hebrews emphasizes: “And no one takes this honor for himself, but only when called by God, just as Aaron was” (Hebrews 5:4). Without a covenant, without a place of encounter, and without these consecrated mediators, there simply was no system of worship. These three keys opened the door.

Conclusion: The Foundations Are in Place

Three keys. One door. The Covenant establishes who may enter. The Tabernacle indicates where. The Priesthood opens the way so that access may be safe and real. Without the three, there is no system. With the three, the impossible becomes possible: a people of flesh and blood living in communion with the God of the universe.

These three keys are not demands God places before opening the door to you. They are the door itself, built by Him, from His side, so that you may cross through it. That is grace: not a vague feeling, but a real architecture that makes possible what would be impossible without it.

The Covenant establishes the relationship, the Tabernacle provides the purified place for joyful encounter, and the Priesthood offers the necessary mediation for meeting with God in that sacred space. With these three keys in hand, the door of the sanctuary opens. Now we can begin to climb the ladder of worship, exploring the different types of offerings and rituals that Leviticus describes.

Every offering we will study, every step of the ladder we will climb together, rests upon this ground that God Himself prepared. He built the path before inviting you to walk it. And the invitation remains open: “I will be their God, and they shall be My people.” An invitation to enjoy the promise that sums it all up: “I will be their God, and they shall be My people” (2 Corinthians 6:16). With these firm foundations, we are ready to discover how this ancient system reveals, in an astonishing way, the path toward Him.

[1] The death of Christ is not equated with the “death of the animal” on the north side of the Bronze Altar. Instead, the NT (Heb 13:11–12) connects His passion and death with the burning of the remains of the ḥaṭṭā’t outside the camp (cf. Lev 4:11–12; 6:30; 16:27). Rather, the Bronze Altar, the Golden Altar, and the Mercy Seat typify the Place of Encounter between God and the people of the covenant. On the other hand, the death of Jesus takes place “outside the gate” for the establishment of the New Covenant, which would give way to a New Place of Encounter: the risen Christ.

[2] From the perspective of general systems theory, the Decalogue functions as the constitutive boundaries of the Levitical system: it defines the normative perimeter within which non-deliberate transgressions can receive cultic treatment, while open violations overflow it and therefore remain outside the reach of the ḥaṭṭā’t. See Ludwig von Bertalanffy, General System Theory: Foundations, Development, Applications (1968), as a conceptual framework for understanding “systems” and “boundaries” analogically applied to normative structures.
