It is difficult for new and sometimes older Christians to fully comprehend sin's effects. From God’s perspective, every facet of sin involves a vile act. However, from man’s viewpoint, though sin can be extremely harmful, the temporary pleasures (Hebrews 11:25) distract from sin's injurious nature. For instance, Proverbs 6:24 warns about the “evil woman.” We might think this to mean that we should stay away from women who say bad things, yet the evil woman does not always speak negatively. In fact, this woman is said to speak with flattery; she says nice things but with impure motives. This warning is so important that it was given on multiple occasions (Proverbs 2:16; Proverbs 6:24; Proverbs 7:5, 21). The warning here is given specifically about a strange woman (a woman other than the man’s wife), but it applies to men and women alike. We ought to always be on guard about those who flatter us with their words.
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).
As we have seen, courage comes from a strength of heart. On the contrary, the Bible likens discouragement (the opposite of courage) to a melted heart (Joshua 2:11). In other words, discouragement takes place when a man’s heart loses strength. The Bible reveals that discouragement comes through various avenues of life. Men become discouraged because of “the way” (i.e., the circumstances of life) (Numbers 21:4). Discouragement also results from fear and unbelief (Deuteronomy 1:28) and the magnitude of a task (1 Chronicles 28:20). Ultimately, discouragement rears its ugly head as a result of a lack of faith in God and His word. Since discouragement and a lack of faith go hand in hand, a discouraged man cannot please God (Hebrews 11:6).
