Mike Leake at SBC Voices has written an article about how we can ruin our children. All of the 10 tips are worth our consideration, but two stood out to me as being particularly helpful and probably not ones we would readily think of.
Display with your life and lips that things are more precious than Christ. The thing you pick can be as insignificant as parking spaces or as significant as a large house. It doesn’t matter. Set something other than Christ as your affection and you are well on your way to shopping for a new millstone.
Help them establish an identity in anything other than Christ. Convince them that they are amazing or worthless it doesn’t matter—just make sure their identity isn’t found in Christ.
