While many people often dwell on their need for more money, better health, or a long vacation and some rest, the Bible indicates that one of humanity's greatest needs is the need for strength! Why strength? Because most of life's problems are attributable to weakness.
According to various sources the Greek word in the New Testament for weakness (asthenes) has these multiple meanings: infirmity, sin, disease, and poverty. Jesus' statement "The flesh is weak" (Mark 14:38), expands the meaning of that word to include all mortal life.
Even as we conclude that weakness is the foundation of a fleshly, matter-based sense of life, we can find the divine remedy for weakness by turning to the very beginning of the Bible where we read: "And the spirit of God moved upon the face of the waters" (Gen. 1:2). Spirit is the opposite of matter. Spirit's primary attribute is strength, and that strength overrules the frailties of matter. The prophet Micah acknowledged this when he exuberantly exclaimed, "Truly I am full of power by the spirit of the Lord" (Micah 3:8).
