To formulate a statement that summarizes the teaching of this book it will be helpful to identify some of the major revelations in Numbers. These constitute the unique values of the book.
The first major value of Numbers is that it reveals the graciousness of God to an extent not previously revealed. We see God's graciousness in His dealings with Israel throughout this book.
In the first section of Numbers (chs. 1-10) God's provision for His people stands out. We see this in the order and purity God specified for the maintenance of the Israelite camp. We see it in the worship God provided for in the camp. We also see it in the movement God prescribed for the camp. God faithfully provided for the needs of His people in these many ways as they prepared to enter the Promised Land.
In the second section of the book (chs. 11-21) God's patience with His people stands out. When the Israelites failed to obey God He did not desert them, but He disciplined them in love. God's patience in dealing with the Israelites did not result from God's weakness, but it was an evidence of His strength. God did not manifest carelessness toward the Israelites by making them wander in the wilderness for 38 years. He manifested carefulness as He used those 38 years to prepare the next generation to obey Him. God disciplined the people for their disobedience, but He always directed them toward the realization of His purpose for them as He disciplined them. The years of wilderness wandering were years of education rather than abandonment. He had similarly prepared Moses for 40 years in the wilderness before the Exodus.
In the third section (chs. 22-36) God's persistence in bringing Israel to the threshold of the land is prominent. God protected Israel from her enemies and provided for her needs. Even though Israel had been unfaithful God persisted in demonstrating faithfulness to the nation He had chosen to bless.
A second major value of this book is the revelation it contains of the gravity of unbelief. This is a revelation of man whereas the first was a revelation of God. Numbers reveals the seriousness of the sin of unbelief that manifests itself in disobedience. The Israelites struggled with unbelief throughout the book, but the most serious instance of it took place at Kadesh Barnea (chs. 13-14).
Numbers reveals the roots of unbelief. These were two causes: a mixed multitude and mixed motives.
The congregation consisted of a combination of believing Israelites and others who had for various reasons joined themselves to the people of God, a mixed multitude. These foreigners joined Israel first at the Exodus (Exod. 12:38), but we find them mixed in with the Israelites throughout Israel's subsequent history (cf. Lev. 24:10-23). This "rabble"was first to complain against God, and their murmuring spread through the camp like a plague periodically (cf. 11:4).
The second cause of unbelief was the mixed motives of the Israelites. They wanted to enjoy God's blessings and obeyed Him to a degree to obtain these. However, they also wanted things that God in His love for them did not want them to have (cf. Gen. 3). The Israelites did not fully commit themselves to God (cf. Rom. 12:1-2). They did not fully allow God to shape them into a nation to fulfill His purpose for them in the world. This too resulted in murmuring. They longed for what they had experienced in Egypt and preferred a comfortable life to the adventurous life to which God had called them. Murmuring is the telltale evidence of selfishness. It arises from a lack of singleminded dedication to God.
The message of Numbers is that everything depends on our attitude toward God. Our attitude toward our opportunities and our circumstances reveals our attitude toward God. If we are not content with what God has brought into our lives, it indicates we may want something different for ourselves than what God wants for us.
When we face a challenge to our faith we must see the difficulty overshadowed by God's presence, power, and promises.
The alternative is to allow the difficulty to block our view of God. The influences of unbelievers and our own doublemindedness will seek to make us behave as the Israelites did. At these times of testing Israel's experiences in Numbers should help us understand what is going on and trust God and obey Him more consistently.
The message of Numbers is a message of comfort on the one hand.
Numbers teaches that the failures of God's people cannot frustrate His plans. In Exodus we saw that the opposition of God's enemies cannot defeat Him. In Numbers we see that the failure of His instruments cannot defeat Him either. God's chosen instruments can postpone God's purposes, but they cannot preclude them.
In Numbers we also see that God always deals with His chosen instruments righteously. He will bless the minority who are faithful to Him even though they live among a majority who are under His discipline for being unfaithful. We see this in God's dealings with Caleb and Joshua. God honors the faithful. He will also faithfully work with those He is disciplining because of unfaithfulness. He will encourage them to experience the greatest blessing they can within the sphere of their discipline. We see this in His dealings with the rebellious generation. Furthermore God will not overlook those who have disobeyed Him because they have established a record of past obedience. He will discipline them too. We see this in God's dealings with Moses. Whereas God honors the faithful He also disciplines the unfaithful.
Numbers further teaches us that God's provisions are always adequate for His people's needs (cf. 2 Cor. 12:9). He sustained the Israelites in the wilderness. Their failures were not a result of God's inadequate provision but their own dissatisfaction with His provision. God Himself is an adequate resource for His people as we go through life (cf. Exod. 14-17).
On the other hand Numbers is also a message of warning. Every believer and every group of believers (e.g., a local church) from time to time face the same challenge to faith that the Israelites faced in the wilderness and at Kadesh. The crisis comes when faith encounters obstacles that only God's supernatural power can overcome. The believer should then proceed against these obstacles in simple confidence in God. Our response will depend on whether we are willing to act on our belief that God's presence, power, and promises can overcome them.
We can fail to realize all that God wants for us if we fail to trust Him.
By way of review Genesis expounds faith. Exodus reveals that faith manifests itself in worship and obedience. Leviticus explains worship more fully. Numbers stresses the importance of obedience.
Numbers shows the importance of obedience by revealing the roots, process, and fruits of disobedience.
