The right kind of sorrow is often needful and brings with it certain benefits. Yet, it is in the joy of the LORD that God's people specifically find strength.
Solomon's mother advised him not to give his strength unto women. He ignored this advice and his wives turned away his heart after other gods.
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.
Man must spend his strength on things that matter. In doing so, we must focus our efforts upon the right things while working through and by God's power.
Prior military personnel know the difficulties associated with functioning as a good soldier. Their training focuses on teaching them how to endure physical and emotional hardships unique to their service. They learn how to follow and obey their chain of command and frequently do things commanded without always understanding the how and why. Paul’s letter to Timothy relates the Christian life to that of a soldier. Timothy, as well as every other faithful Christian, is challenged with difficulties based solely on the fact that he is a follower of the Lord Jesus Christ. Paul instructed Timothy how to react during those times when the difficulties arise. According to Paul, Timothy was to “endure hardness, as a good soldier of Jesus Christ.” The Christian life is not supposed to be a life of ease. Fortunately, with Christ in focus, things take on a clearer focus with a notable purpose and plan. The Christian life contains “hardness” but submission to the true Commander in Chief helps the suffering seem like a light affliction (2 Corinthians 4:17). Like the good soldier, the faithful Christian needs to learn how to endure hardness in order to avoid bitterness and bewilderment during life’s battles.
