Sermon Resources - Dr. Toby Holt
What was manna in the Bible — and why did God send bread from heaven? Six weeks after leaving Egypt, Israel ran out of food in the wilderness and turned on Moses with bitter complaints. God responded not with judgment but with bread — thin flakes that appeared on the ground every morning for forty years, in exact supply for each day's need. In this sermon on Exodus 16–17, Dr. Toby Holt examines what the manna was and why it was given on a pattern of six days with a double portion before the Sabbath, why Jesus said "I am the bread of life" and described himself as the true manna come down from heaven in John 6, and what the water struck from the rock at Meribah teaches about the patience and provision of God.

Questions This Sermon Answers:
1. Why did the Israelites complain so quickly after the Exodus?
Israel's rapid descent from the miracle of the Red Sea to bitter complaining is shocking — and entirely human. The pattern reveals what Reformed theology calls the depravity of the heart: the natural human tendency to forget God's past mercies when present needs press. The Israelites had experienced extraordinary deliverance, yet physical hunger and thirst quickly dominated their consciousness. Their complaints are not unique to ancient Israel — they are the universal human response to hardship when faith is shallow.
2. What was manna?
Manna is described as a fine flake-like substance appearing on the ground each morning — "like white coriander seed" and tasting "like wafers made with honey" (Exodus 16:31). It could be baked or boiled, but it could not be hoarded — it rotted overnight except on the eve of the Sabbath, when a double portion could be gathered. Its name in Hebrew may mean "What is it?" — capturing Israel's initial bewilderment. Jesus explicitly identifies Himself as the true manna in John 6:32–35: "I am the bread of life."
3. What is the theological significance of manna?
Manna taught daily dependence. Unlike annual harvests, manna required daily gathering — it could not be stockpiled. This enforced a daily posture of trust. Deuteronomy 8:3 interprets it explicitly: "He humbled you, caused you to hunger, and fed you with manna... that He might make you know that man shall not live by bread alone, but man lives by every word that proceeds from the mouth of the LORD." Jesus quotes this verse in His wilderness temptation — identifying Himself as both the giver and the substance of true bread.
4. How does the manna point to Christ?
In John 6, Jesus explicitly contrasts the manna Moses gave with the bread He gives: "For the bread of God is He who comes down from heaven and gives life to the world" (John 6:33). The parallels are deliberate: manna came from heaven; Christ came from heaven. Manna sustained physical life; Christ gives eternal life. Manna was received daily through gathering; Christ is received through faith. Manna ceased when Israel entered Canaan; Christ is the bread of life forever. John 6 is the New Testament's authoritative commentary on Exodus 16.
5. What happened at Rephidim and why does it matter?
At Rephidim, Israel ran out of water and threatened to stone Moses. God commanded Moses to strike a specific rock with his staff, and water came out. Paul identifies this rock in 1 Corinthians 10:4: "that Rock was Christ." The rock was struck once (Exodus 17) — and water flowed. When Moses struck the rock a second time at Meribah (Numbers 20) in disobedience, he was barred from the Promised Land, because the rock was to be struck only once. Christ was crucified once; the water of life flows from that single, unrepeatable event.
6. What does "testing God" mean in this passage?
Exodus 17:7 records Moses naming the place "Massah and Meribah" — testing and quarreling — because Israel "tested the LORD, saying, 'Is the LORD among us or not?'" This is the sin Jesus quotes Deuteronomy 6:16 against in His temptation: "You shall not tempt the LORD your God." Testing God means demanding that He prove Himself on our terms rather than trusting His word. It is the opposite of faith. Jesus, in the wilderness, refused to demand a sign from God — He trusted the Father's word.
7. How does God respond to Israel's persistent grumbling?
God responds with provision, not punishment — at least initially. The consistent pattern of Exodus 16–17 is divine patience meeting human ingratitude with supernatural supply. This is not because Israel deserved it but because God had bound Himself to them by covenant. Manna fell every morning for forty years. Water followed them through the wilderness. Paul interprets this in 1 Corinthians 10 as a lesson in grace — and a warning: God provided for grumblers, but He also disciplined them severely when their unbelief became persistent rebellion.
8. What do these miracles teach about Christian provision?
The manna and water from the rock teach that God's provision is real, daily, sufficient, and tied to His covenant relationship with His people. They also teach that provision does not immunize against unbelief — Israel had both miracles and still fell in the wilderness (1 Corinthians 10:5). The Christian is called not merely to receive God's provision but to trust His person. "Give us this day our daily bread" is not a prayer for stockpiling — it is a daily declaration of dependence on the One who gives bread from heaven.
Key Theological Points:
1. Daily Dependence as Spiritual Formation
The design of manna — given daily, unable to be hoarded — was an intentional school of dependence. God did not give Israel a six-month supply; He gave them today's bread today. This enforced a daily return to God in trust. Westminster Larger Catechism Q. 193 interprets "daily bread" in the Lord's Prayer as a petition for God's provision of all outward blessings, acknowledging our complete dependence on His fatherly care. The manna is the Old Testament curriculum for the lesson Christ teaches in Matthew 6:25–34: do not worry about tomorrow.
2. Christ as the True Bread and Living Water
Both the manna and the water from the rock find their fulfillment in Christ. John 6 and John 4 make this explicit. Jesus tells the Samaritan woman: "Whoever drinks of this water will thirst again, but whoever drinks of the water that I shall give him will never thirst" (John 4:13–14). Jesus tells the crowd: "I am the bread of life. He who comes to Me shall never hunger" (John 6:35). The wilderness miracles were real events that simultaneously served as enacted prophecy, pointing forward to the One in whom every human need is met.
3. Grace Toward the Undeserving
Israel's grumbling was sinful — and God fed them anyway. This is grace. Not because God approves of grumbling, but because His covenant faithfulness is not contingent on Israel's faithfulness. Spurgeon preached: "God's mercy is not a reward for our goodness but a revelation of His character." The same is true in the gospel: God's provision of Christ came not when humanity deserved it — "while we were still sinners, Christ died for us" (Romans 5:8). Exodus 16–17 is a wilderness sermon on unmerited divine provision.
4. The Text: Exodus 17:5–6 (NKJV)
"And the LORD said to Moses, 'Go on before the people, and take with you some of the elders of Israel. Also take in your hand your rod with which you struck the river, and go. Behold, I will stand before you there on the rock in Horeb; and you shall strike the rock, and water will come out of it, that the people may drink.' And Moses did so in the sight of the elders of Israel."
