How many kings?

I've been hearing this song on the radio a lot lately and really love it.

Chorus:
"How many kings, stepped down from their thrones?
How many lords have abandoned their homes?
How many greats have become the least for me?
How many Gods have poured out their hearts
To romance a world that has torn all apart?
How many fathers gave up their sons for me?
Only one did that for me..."

It makes me wonder how many believe, but still don't have time for God, time for church, time to teach their families about faith and God's greatest sacrifice? Because I am a believer, I feel a enormous sense of responsibility to educate my children with regard to faith because society today is only going to try to lead them astray. I love them too much not work tirelessly trying to lead them to God.
