We are to “fight the good fight of faith” (1 Timothy 6:12). This battle makes it imperative that we understand “we do not war after the flesh” (2 Corinthians 10:3). Unlike many of the cults, we do not use physical weaponry in our attempts to accomplish the will of God. No physical sword or weaponry can convert the lost to Christ; however, the Bible does instruct us to use the sword of the Spirit (Ephesians 6:17). In like manner, we do not have to resort to using physical weaponry to bring about our desired results during the spiritual battles. Instead, we flee to God's throne to find grace to help in time of need (Hebrews 4:16). We must insure that we do not carelessly allow ourselves to believe that the spiritual weapons are inferior to carnal weaponry. The Bible enforces this thought by reminding us that our weapons are “mighty through God to the pulling down of strong holds” (2 Corinthians 10:4).
Carnality becomes increasingly difficult to hide. Eventually, it clearly manifests itself in our daily actions. The carnality of the Corinthian believers showed itself in their relationship amongst their body of believers. They began to envy one another, eventually leading to strife and divisions amongst the group. When Paul learned of their failings, he knew carnality was at the root of the problem. Another action openly revealing the carnality of the people was their relentless desire to associate themselves with particular Bible teachers. They assumed an association with someone as well respected as Paul or Apollos would give them a spiritual boost among other believers. Considering their actions, Paul knew these believers were “yet carnal.”
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).
