Buckle your seatbelts, because today we’re going to cover five verses: Hebrews 3:15-19 (woohoo!). But we’re going to focus on just one word. Verses 15-19 serve as a commentary 7-11, which recalled Israel’s rebellion and subsequent forty years of desert wandering. The writer of Hebrews, in describing this band of wanderers said that they “rebelled” (v. 16), they “sinned” (v. 17), and they “disobeyed” (v. 18). All of these verbs culminate in one word, see if you can figure it out: “So we see that they were not able to enter, because of their unbelief” (v. 19). Rebellion, sin, and disobedience are all symptoms – the deadly disease that killed an entire generation of Israelites was unbelief. Here’s the key: those who believed and those who did not believe heard the same promise from God: “See, I have given you this land” (Deuteronomy 1:8). An entire generation of “bodies fell in the desert” (v. 17).
But they weren’t the first to doubt God. A long, long time ago God told a couple in a garden, “You must not eat from the tree of the knowledge of good and evil, for when you eat of it you will surely die” (Genesis 2:17). Then along came the serpent who asked, “Did God really say, ‘You must not eat from any tree in the garden’?” (3:1). The serpent wasn’t trying to clarify what God had told them. His question went to Adam and Eve’s heart: “Did God really mean what He said?” We see that in verse 8 when he completely and exactly contradicts what they had heard: “You will not surely die.” They took the bait because, in their hearts, they didn’t believe His word was true.
The essence of unbelief is not rejecting God but rather doubting if God is trustworthy. Like Adam and Eve and the Israelites, we act on our unbelief with rebellion, sin, and disobedience. To believe God is to take Him at His Word – that He is who He says He is and will do what He says He will do* – and then act on what we heard. That’s what we’ll find in the “Hall of Faith” a few chapters ahead. So the question then is, Beloved, do you believe God?
