"The just shall live by faith" is both a statement of fact about the basis of a Christian's life and a command. It is so important that it appears once in the Old Testament and three times in the New (Habakkuk 2:4; Romans 1:17; Galatians 3:11). In each case, the context is somewhat different, but its importance to a Christian's salvation is not lost.
The concept is not difficult to understand. Paul further clarifies it in II Corinthians 5:7: "For we walk by faith, and not by sight." A simple definition of faith in Webster's New World Dictionary is "complete trust, confidence, or reliance." At the end of the definitions, "belief" is listed as a synonym. Belief means "faith, esp. religious faith; trust or confidence." The dictionary definitions show that the two words are virtually synonymous. However, in the Bible and in practical application a very wide difference separates merely believing and living by faith.
The practical application of faith is more than simply acknowledging the reality of God. Living by faith involves qualities that are better expressed by the word "trust." This kind of faith produces loyalty or faithfulness expressed in the Christian's life by works of obedience.
Do you think for a moment that the Israelites in the wilderness disbelieved that God existed? Some few may have argued that the miracles they had experienced from the arrival of Moses in Egypt until they died in the wilderness were nothing more than natural phenomena. There are always some doubters and scoffers of that sort (II Peter 3:3-7).
But the vast majority of Israelites could not deny to themselves God's mighty acts on their behalf. They had heard the voice of God at Mount Sinai, had seen a wind from God part the Red Sea, and had escaped death on Passover while the Egyptian firstborn had died. But when God required a higher level of obedience to follow His cloud across the wilderness and depend on Him to supply their every need, the record shows they did not trust Him. Their loyalty dissolved, and they rebelled! They did not have it within them to live, or walk, by faith.

Wandering the Wilderness in Faith
Israel feared the warfare that they knew would confront them when they stepped over the border—and they drew back. Their drawing back in fear was a serious sin, as Numbers 14:9 shows. Drawing back in fear or failing to enter the fray is on a par with rebellion because it is a rejection of God's Word, a despising of His promise.

This is not the first time faith or its opposite, unbelief, is mentioned in Hebrews. The very purpose of the entire epistle is to recapture, build, and sustain in its recipients their faith in the superiority of Jesus Christ Himself and in His message, the gospel of the Kingdom of God.
Notice the strong, earlier statements Paul makes regarding unbelief:
» Hebrews 3:12, 19: Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God. . . . So we see that [the Israelites in the wilderness] could not enter in[to the Promised Land] because of unbelief.
» Hebrews 4:2: For indeed the gospel was preached to us as well as to them; but the word which they heard did not profit them, not being mixed with faith in those who heard it.
These are weighty statements. The Israelites failed to accomplish their responsibility of walking from Egypt to the Promised Land primarily because of one weak element in their character. They did not believe God or His messenger Moses. They did not listen thoughtfully or yieldingly.
Because of the warning contained within Hebrews 10:35-39, chapter 11 places the virtue of faith in direct contrast to the sin of unbelief by exposing what unbelief caused to occur. The Israelites drew back in fear rather than trusting God and boldly going forward. Thus, the main point of the epistle of Hebrews is that they will be destroyed who, by failing to put their trust in the living God, shrink back from this Christian war we have been called to fight, whereas those who believe will be saved.
