Each phase of life bears the marks of certain strengths and weaknesses. In youth, man has a great amount of zeal. In fact, the Bible points out that “the glory of young men is their strength.” A young man might have the fortitude, strength, and stamina to accomplish great things, but his limited knowledge hinders his ability to accomplish greatness. As time elapses, man learns from both failure and success. He obtains the knowledge and enjoys the wisdom that often eluded him during his youth. His glory no longer resides in his strength, but his beauty is now “the gray head.” The very thing that limited his ability to accomplish great things in youth is now a virtue he has achieved. The glory of his youth may have departed, but there remains hope. He has the knowledge but lacks the strength he once possessed. Fortunately, he can invest his knowledge into those who still retain their youthful vitality.
A tender heart quickly and readily yields when offered correction; however, as a heart becomes hardened, the times of yielding become fewer and farther apart. During the hardening process, the individual finds the true nature of the heart more difficult to grasp. As the heart further hardens, the individual finds himself involved in further defiance. The mischief may start as seemingly insignificant, but a hardening heart will ultimately lead to greater depths of wickedness, some seemingly unimaginable only a short time ago. Some of the worst sins committed in the Bible by God's people were committed by those who shortly before had displayed a tender heart. Yet, they allowed their hearts to be hardened by the deceitfulness of sin.
