Parents who love their children delight in blessing them. However, have you noticed how consistently doing the same kind thing for someone can (usually does) cause that blessing to become expected? Then if for some reason that blessing is not done, the blesser (you) is resented instead of appreciated. If that continues, over time bitterness is likely. Oh, how quickly the flesh develops an entitlement mentality.

Some symptoms your child is developing an entitlement mentality might be: ungratefulness, laziness, and resentment toward you. Real gratitude is deeper than him replying with a simple “thank you.” Observe how he responds when an expected blessing is not forthcoming, or you ask him to do an additional job? 

“Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled” (Hebrews 12:15).
