When man trusts in nothing, he receives nothing in return. That is the primary point of Job 15:31. Yet, that is not the only truth being taught. It is also true that people should not trust in anything of little to no value. This would include beauty (Ezekiel 16:15; Proverbs 31:30) and riches (Psalm 62:10). Unfortunately, many in this world have become accustomed to trust in their intellect, beauty, and riches. The end result is borne out in the entertainment and business worlds, but the seeds of this troubling problem usually begin in early childhood. Young people often hear the emphasis placed upon their appearance or education as the primary means of getting the things that these young people want most in life.
Believers should be zealous of good works, but their zeal must not spring from a position of ignorance. The Bible points to the Jews as a zealous people, but their zeal was not according to knowledge. Nobody worked harder trying to reach a righteous state than did the Jews. However, they failed to realize that true righteousness comes as an unmerited gift from God. Yet, the Jews were “ignorant of God's righteousness,” and went “about to establish their own righteousness” (Romans 10:3). Paul repeatedly testified concerning the futility of trying to earn God's favour through one’s own efforts (Acts 22:3; Philippians 3:6). Before Paul came to know Christ, he thought he should fight against Christ’s followers and zealously persecute the church of God. He even placed many of the new believers into prison and caused their deaths. Yet, he declared that all this was done in ignorance (1 Timothy 1:13). He, like the Jews, had a tremendous zeal, but that zeal was not according to knowledge.
As Moses recounted Israel’s time in the wilderness, he reminded God’s people of the reasons for their failure to enter into the land of promise. He rehearsed how it was the people who approached him requesting that spies first be sent into the land to explore it. If the people had trusted God, surveying the land would have been unnecessary. Yet, the people doubted God’s provisions so Moses sent in the spies. When they returned, they expressed stories of giants and walled cities that made the people fear to carry out God’s will. The spies’ report '"discouraged” (Deuteronomy 1:28) the hearts of the people. This loss of courage yielded an unbelief in the people (Deuteronomy 1:32), greatly displeasing the Lord (Hebrews 3:17-19).
