I read this quote from the Puritan Cotton Mather on the importance of keeping the main thing the main thing for Christian parents.

Before all, and above all, ’tis the knowledge of the Christian religion that parents are to teach their children…The knowledge of other things, though it be never so desirable an accomplishment for them, our children may arrive to eternal happiness without it…But the knowledge of the godly doctrine in the words of the Lord Jesus Christ is of a million times more necessity for them.

We can stop feeling guilty about our children not being in a sports team, or being unable to attend music lessons or other activities. These are good things, but if we forgo these because spiritual development and family relationships are more important to us, we do well.
