day no. 16,384: we must instruct our children

"Suffice it to say here that when I say that we should instruct our children, I mean that WE should do it, not [someone else.]" — G.K. Chesterton, What's Wrong With The World (emphasis mine)

We must instruct our children. It is inescapable. Everything we do teaches something. We either teach them that we took responsibility for them or that we didn't. We teach them what is worth learning and where to go to find it. God has given this responsibility to parents. A father who abandons his children still teaches them something. His absence teaches a powerful lesson about life. A mother in the marketplace instead of her home is still teaching her child something about the home.

“We must instruct our children” presupposes "we" to be each parent considered individually and “our" to be each child considered respectively to his or her parents. The parent is responsible for the child and the child is responsible to the parent. There can be no concession to the notion that the child, in his natural state, is the responsibility of the State. 

A parent is permitted to supplement their primary effort with outside support, but they cannot shift their primary effort to be primarily someone else's. A Christian parent, all the more then, must carefully consider what supplements are permissible and profitable.

1 Corinthians 6:12

All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.

Be careful when considering your options not to give yourself or your children too quickly or too completely to something that will require you to ask to have them back.

Romans 6:16

Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey?

If you surrender your children to them, you will find that you need their permission to get them back.

1 Corinthians 10:23

All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.

Also, be careful not to assume that all help is equally helpful. Some things help in one way, but hurt in another. The school may be willing to teach your children, but what is taught will contradict Christ's law.
