Strength is not tested or demonstrated during times of ease. Rather, it is during times of adversity that one finds out just how strong he is.
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.
Those with their ear toward the world have many accessible teachers. Unfortunately, far too frequently, that which is being taught contradicts the plain teaching of scripture. In order to combat the propagation of false teaching, the Lord calls upon His people to teach the truth. God placed men within the New Testament church to spread the truth through teaching and preaching (Acts 13:1). He placed older men and women in the church in order to teach the younger men and women (Titus 2:1-8). He placed godly moms and dads in the home to teach the children. Every believer should have a desire to come to a point where he or she can teach others. According to the scriptures, this is the will of God (Hebrews 5:12).
