My four year old already knows about people “leaning on their own understanding” instead of on God’s Word and asks me about it when we read things in certain books.

I agree, BUT...

Just telling someone that he or she ought to accept God's Word as truth won't work if the individual is not open to the possibility.

First, you must open them up to the possibility. After all, you can lead a horse to water, but you can't make it drink. [Only God can do that.]

My primary responsibility is for those in my house. I’m doing what I can.

As for others, they have to make the choice themselves.
Deu 4:29
But from there you will seek the LORD your God, and you will find Him if you seek Him with all your heart and with all your soul.
