Expository Thoughts on Mark

We ought to remember this in the training and education of children. In all our management we must never forget, that the seeds of all mischief and wickedness are in their hearts... They carry within them a heart ready for any sin, and until that heart is changed they are not safe, whatever we do... But no bad companion teaches a boy or girl half as much sin as their own hearts will suggest to them, unless they are renewed by the Spirit.
