This succinct statement illustrates what made the difference between those who succeeded in living by faith and entered the Promised Land and those who left Egypt but died during the pilgrimage: Those who succeeded “saw” God.
This is perhaps the simplest and clearest explanation of the nature of faith in the entire Bible. Hebrews is written to a group of people undergoing severe trials, and the author encourages and counsels them to persevere through them and remain on track for the Kingdom of God. At this point, Moses is the specific illustration of living by faith. In his relationship with God, he is described as being sustained in perseverance as if he literally saw God with His bodily eyes.
Hebrews 11:1 explains, “Now faith is the substance of things hoped for, the evidence of things not seen.” The author is saying that faith is the confident conviction that, like the foundation of a building, stands under and supports a life lived by faith in the invisible God. This brings up an important question: How can a person live by faith if he does not have sufficient knowledge of the sovereign greatness, closeness, and awesome grace of God? In the mercy that He has already given, God has shown enough of Himself to allow us to begin a relationship with Him. Of course, we need more to come to know Him and fear Him as He desires.
A recent Barna poll reported that over 80% of Americans believe God exists. Yet, how is their level of knowledge about Him affecting their conduct? Clearly, it is not supporting moral living to any great extent. This fact triggers the thought that the great immorality of the American people reveals that they are not very concerned about being answerable to Him. They have heard of Him but do not know Him.
