Man is not promised an endless supply of strength for him to store up. Rather, God promises to provide the necessary grace and strength for the present trials.
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).
