We need to remain childlike. Children don't dream of being insignificant.
Doesn’t it honor Him more when His children no longer see themselves only as sinners saved by grace, but now as heirs of God? Isn’t it a greater form of humility to believe Him when He says we are precious in His sight when we don’t feel very precious?
Obviously, there are children who have been victims of abuse or neglect, so they've got a lot of emotional challenges.
