There is a notion that makes people think all children must behave foolishly while growing up. It is a mentality carried over the years about children and it partially true for the children of the world. Some people even say its normal and ok for children to behave foolishly as they will outgrow such characters.
Unfortunately some children never outgrow these attitudes especially when not corrected on time, such foolishness grows into stubbornness and other negative characters.
Children can make mistakes but It is also 100% possible for a child to be wise and not display some foolish characters from a very tender age. This can be seen in the life of Timothy who was trained by his mother Eunice and grand mother Lios in the bible.(2nd Timothy 1:5)
The bible states that Timothy was wise from childhood through the word of God he was introduced to.(2nd Timothy 3:15). It is only the word of God that has the capacity to make a child wise. It is powerful to control the character of a child.
Every parent/guardian should make their job easier by introducing the word of God on time into the lives of their children.
