In the book, Answering Your Kids’ Toughest Questions (2014), Jessica Thompson writes on page 153:

“Every day our children hear messages of bad news, and they are told that all the answers they need are inside of themselves, or told to believe or trust in themselves.  Why?  Because our children are sinners, and neither we, nor they, are trustworthy.  This bad news is a poison advertised as a cure.  Anti-gospel messages tell children to trust in their own goodness and faithfulness.  But at the end of the day, how much goodness or faithfulness does any one of us actually have?  This is simply bad news.  We all need a drink from outside our own hearts.  We need the living water Christ offered:

If anyone thirsts, let him come to me and drink.  Whoever believes in me, as the Scripture has said, “Out of his heart will flow rivers of living water” (John 7:37-38).
