Did you ever walk through a cemetery and take time to read the inscriptions on the headstones? Some are poignant, some are humorous, and some just give the name and dates of birth and death. But, all of them are reminders that life is brief, death is sure, and how we live will be remembered in eternity (Eccl. 11:9-12:7). Truly, a life lived only for this world, without “fearing God and keeping His commandments,” is “vanity of vanities” (Eccl. 12:8).

No more vivid example of this exists than the death of the Israelites whom God led out of Egyptian slavery. The Scriptures explain why that generation did not enter the land of promise:

“For who, having heard, rebelled? Indeed, was it not all who came out of Egypt, led by Moses? Now with whom was He angry forty years? Was it not with those who sinned, whose corpses fell in the wilderness? And to whom did He swear that they would not enter His rest, but to those who did not obey? So we see that they could not enter in because of unbelief” (Heb. 3:16-19).

Imagine with me for a moment the enormous number of graves that were dug in the wilderness of Sinai during the forty years Israel wandered there. Before leaving Mt. Sinai, a standing army of 603,550 men over twenty years of age was numbered (Num. 1:3, 45-46). Accounting for women, children and the elderly, we are well within reason to believe upwards of 2 million Israelites left Egypt bound for Canaan. Yet, only two men of those above twenty years old enter the land; Joshua and Caleb (Deut. 1:35-36).

A conservative estimate based on these numbers suggests over a million deaths occurred during the period of wandering. The wilderness of Sinai began the graveyard of rebels – each grave a landmark to blessings wasted and the tragic fruit of sin.

The rebellion of Israel in the wilderness has been written to teach us not to follow their example of rebellion (Rom. 15:4). We do well to ponder those wilderness graves, “lest anyone fall after the same example of disobedience” (Heb. 4:11).

Let us imagine the headstones of those buried in the wilderness. They teach us valuable lessons and warn us not to fall away from God.

“Here lies Unbelief: Disobedient to the end.” The sin of unbelief reveals itself in disobedience (Heb. 4:18-19). In other words, disobedience occurs when there is a lack of faith. Just like Israel in the wilderness, a Christian can develop “an evil heart of unbelief in departing from the living God” (Heb. 3:12). Although Israel saw God’s mighty works in Egypt and walked through the parted waters of the Red Sea, although God gave them water from the rocks, and quail and manna from heaven, still their hearts did not trust God. Although our sins have been cleansed by the blood of Jesus, we can fall back into sin through fearful, faltering and failing faith. Therefore, “watch, stand fast in the faith, be brave, be strong” (1 Cor. 16:13). It is possible to deceive ourselves about our faith. If we are not obeying the Lord, our faith is not strong. There were graves in the wilderness because Israel did not believe and obey God with her whole heart.

“Here lies Rebellion: Irreverent in life, forgotten in death.” Israel greatly dishonored God with her idolatry, even though He delivered her, protected her, provisioned her and guided her. Israel repaid God’s faithfulness by breaking His law and worshiping a golden calf, even as He was giving Moses His law on two tablets of stone (Exo. 32:1-8, 15-16). Strikingly parallel are Christians who give lip-service to the gospel of Christ, yet serve the gods they have made: covetousness, pleasure and self-satisfaction. Oh yes, idolatry is still alive and well. God will not be disrespected; He is holy, and we must respect His holiness (1 Pet. 1:15-16). We must honor God with God-fearing priorities in our lives. Where there is godly fear there is a yearning to love and obey the Lord with all the heart, knowing that God accepts those who fear Him and work righteousness (Acts 10:34-35). When we disrespect the Bible, the word of God, we disrespect God. Such irreverence will prepare for us a grave in the wilderness.

“Here lies Lust: Consumed by evil desire.” Thousands upon thousands in Israel craved evil things, and were buried in the desert (1 Cor. 10:6, 8; Num. 4, 34; 25:1-9). Will we ever learn that evil things always promise more than they can deliver (Heb. 11:25; 2 Pet. 2:19)? The lust of the flesh and the lust of the eyes turn the saint’s attention away from the Holy One to the fleeting folly of the world’s unholiness (1 Jno. 2:15-17). When a person yields to the intense cravings of sexual sins, he or she is often reduced to poverty, and is most definitely reduced to spiritual poverty (cf. Prov. 6:26). Fill yourself with the desire for good things, and God will fill you up.

“Here lies Certainty: He reaped what he sowed.” God did not treat Israel unjustly: “Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap” (Gal. 6:7). While we defend our freewill to “do what we think is right,” we must also acknowledge God’s punishment when we choose what is against the will of God (Gal. 6:8; Jno. 12:48). We cannot sow sin and reap heaven’s eternal life. This compels us to “test all things; hold fast what is good. Abstain from every form of evil” so that our grave will not be in the wilderness of sin (2 Thess. 3:21-22).
