The Bible likens a mature Christian to one who exercises. Exercise involves work for it to be most profitable. Many people start exercising with exuberance and zeal, yet quit when the workout begins to get difficult. This too unfortunately applies to those who start out wanting to live a godly life. Too many Christians quit simply because spiritual growth takes a lot of hard work and effort. Today’s passage contrasts the difference between a babe in Christ and a believer enjoying the meat of God’s word. The babe enjoys the milk of God’s word (the basic truths) but the milk limits the extent of his growth; whereas, the mature Christian wants to grow stronger through learning the truths that babes cannot yet handle. The strong Christian exercises his senses enabling him to discern between good and evil. He works hard. He does not quit though times get tough. He keeps reading his Bible. He keeps praying. He keeps obeying the Lord. When he stumbles, he simply picks himself back up, brushes himself off, and keeps moving forward, onward, and upward. So get up and go!
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).
