3. Hear and Obey the Lord (vv. 7b-11). The Word of God is a vital part of Christian worship, especially in this age when inventing clever new worship forms is a common practice and novelty is replacing theology. Hearing and heeding God’s Word must be central if our worship, private or corporate, is to be truly Christian. It isn’t enough for God to hear my voice; I must hear His voice as the Word of God is read, preached, and taught. The Scriptures written centuries ago have authority today, and we have no right to ignore them, change them, or disobey them. We are to respond to God’s Word now, when we hear it, and not just later in the week when we review our sermon notes or listen to the recorded message. How tragic when worshippers go home with full notebooks and empty hearts! (See Heb. 3:7–4:13, where this passage is applied to the church today, warning us not to harden our hearts against the Lord.) The way we treat the Word of God is the way we treat the God of the Word. Jesus admonishes us to take heed that we hear (Matt. 13:9), take heed what we hear (Mark 4:24), and take heed how we hear (Luke 8:18).

The writer reached back and cited two tragic events in the history of Israel–the nation’s complaining at Rephidim (Ex. 17:1-7) and its unbelief and disobedience at Kadesh Barnea (Num. 13–14). The Jews had seen God’s wonderful works in Egypt, especially His defeat of the Egyptian army when He opened and closed the Red Sea–but they refused to trust Him for their daily needs. No sooner were they liberated from Egypt than they complained that they were hungry, so He sent them the manna, the bread of heaven (Ex. 16). When they arrived at Rephidim, the people complained again because they were thirsty (Ex. 17:1-7). Instead of trusting God, they blamed God and His servant Moses. God graciously gave them water out of the rock, but Moses commemorated the event with two new names for the site: Meribah means “strife, quarreling, contention,” and Massah means “testing.” (See also Num. 20:1-13.) Instead of trusting God, the people had contended with God and had even tempted Him by their arrogant attitude and words. He could have sent immediate judgment, and they dared Him to act.

Israel spent a year and two months at Sinai (Num. 10:11) and then departed for Kadesh Barnea, the gateway into Canaan (Num. 13–14). Here they refused to trust the Lord and obey His orders to enter the land and claim their inheritance. In spite of all they had seen Him do, the Israelites hardened their hearts and refused to do God’s will. God judged His people at Kadesh Barnea and consigned them to thirty-eight years in the wilderness while the older generation died off. It was the world’s longest funeral march. “They should not enter into my rest” (v. 11; Num. 14:26-38). The writer of Hebrews used this event to warn Christians not to harden their hearts and thereby fail to claim what God had for them to do, to receive, and to enjoy. God has a perfect plan for each of His children (Eph. 2:10), and we claim that inheritance by faith in God’s Word, the kind of faith that leads to obedience.

In Moses’ day, God’s “rest” was the land of Canaan, where the Jews would do no more wandering (Ex. 33:14; Deut. 12:9-10; Josh. 1:13, 15). But Hebrews 4 broadens the meaning of “rest” to include the salvation rest and inheritance we have in Christ (Matt. 11:28-30; Eph. 1:3, 11, 15-23) and the future eternal “Sabbath rest” in glory (Heb. 4:9; Rev. 14:13). Hebrews 1–4 is God’s admonition to the church today to live by faith, and “faith comes by hearing, and hearing by the word of God” (Rom. 10:17 nkjv). Because the Jews refused to hear His Word but hardened their hearts instead, God was disgusted with His people, and all the people twenty years old and older died during that wilderness journey. We harden our hearts when we see what God can do but refuse to trust Him so He can do it for us. We fail to cultivate a godly heart that fears and honors the Lord. It is a grievous sin to ask for the gifts (food, water, etc.) but ignore the Giver, and the consequences are painful.
