When Adam transgressed, he affected and infected all that would come after him. When God created man, He did so after His own likeness (Genesis 1:26; Genesis 5:1), but when Adam bore a son after the fall, the Bible says that Adam “begat a son in his own likeness” (Genesis 5:3). Adam’s sin came with dire consequences experienced by all. All those born of Adam’s seed bear Adam’s image (1 Corinthians 15:47-49) and the Bible points out that “in Adam all die” (1 Corinthians 15:22). At the same time, no man faces the eternal judgment of God for bearing Adam’s image, but he does so based upon his own practice of sin and refusal to accept God’s free gift of salvation through His Son, Jesus Christ.
Much of a young person’s character or lack thereof is demonstrated in his behaviour toward adults and especially the elderly. In Isaiah chapter 3, the Bible speaks of a time when the judgment of God will be upon His people, and one of the characteristics of the day will be that “the child shall behave himself proudly against the ancient.” The prophet Elisha dealt with such children when they came out of the city mocking him saying, “Go up, thou bald head; go up, thou bald head” (2 Kings 2:23). Apparently, Job endured a similar problem as he said, “young children despised me; I arose, and they spake against me” (Job 19:18). Children can be cruel, and in doing so they reveal an evil heart displeasing to the Lord. It is never a good idea to encourage children to be insolent and impolite toward adults.
