I have a son, who is 6 years old; he has plenty of energy, which he doesn't always expend in the most constructive of ways. But, of course, he is my son, and I love him.
I thought that I'd have a look in the Bible for places where God's relationship with us is likened to that of a parent's with his (or her) child. And since I've been reading recently through the book of Malachi, that's where I started. And I came across Malachi 3:17. God says, "I treat them with the same consideration and kindness that parents give the child who honors them." Not quite the unconditional love that some speak of. We should expect respect from our children (seeking, of course, at all times to deserve it).
