You do not want to grow up to be a hoddy-doddy. According to the American Dictionary of the English Language by Daniel Webster (1828), a hoddy-doddy is a foolish person. According to Scripture, there are several things that justify labeling someone as a hoddy-doddy.
The person who says there is no God is a fool (Psalm 14:1). Anyone who refuses to gain wisdom or listen to instruction is a fool (Proverbs 1:7). Those that laugh at sin and find entertainment in it are foolish (Proverbs 14:9). The person who ignores God’s law and makes up his own laws by which to live is a fool (Proverbs 12:15; Romans 1:22). The person who hordes material things and has no interest in helping others or giving back to God is a fool (Luke 12:20). Those that do not righteously consider how they are walking in this world are fools (Ephesians 5:15). Those who would allow someone to draw them away from obeying God are foolish (Galatians 3:1).
It is not good to be seen by God as a hoddy-doddy. The right thing to do is to study the Bible. Learn all you can from it. Obey God. Teach others to obey Him so that none of them will be known as a hoddy-doddy. If any of this is hard to understand, ask an adult to help you.
