Here are just a few more quotes from the great little book Hints for Parents. From these you can see the theological awareness and pastoral earnestness of the book.
“To the religious character of our children, everything else ought to be made subservient. Our high privilege is to ‘bring up children in the nurture and admonition of the Lord.’ Whatever others may say or do, Christian parents should choose for their children that ‘good part which shall not be taken from them.’ To them, everything else should be like dust.” 27
“Now, you must recognize a mournful fact: Your child is depraved. You will fail utterly to educate him if you don’t recognize this sad reality.” 35
“What a man ought to know, he ought to begin to know very early. The great moral principles, which enlighten his adult conscience and character, ought to penetrate and work on his dark mind in childhood.” 35
“Depraved humans have sacrificed their children to false gods, burning them on the white hot hands of Moloch. Would you do ten thousand times worse by neglecting the heart of your child?” 57
“[quote from Tedd Tripp] Nothing will provide your children with an understanding of the power of the gospel like your love and dependence on God.” 57
