I've always remembered Hebrews 12, talking about a Father's discipline for his son.
"Our fathers disciplined us for a little while as they thought best; but God disciplines us for our good, that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it." (Heb. 12:10-11)
I've always understood it to mean that God will discipline us, and it's for our good. He does it out of his love, though at the moment we wonder why he would put us through it.
Now I think I'm really starting to understand it... from a father's perspective.
Evan is a good boy. He REALLY is. Everyone who comes to see him mentions how he doesn't cry very much. To be honest, he rarely does full-on cry beyond a wimper.
But I noticed, as I assume it is with all babies, Evan punctures my ears whenever I open up his diaper to change.
I heard recently from a friend that it's because the baby is so used to being wrapped up tightly, bundled together, just like when he was in the safety of mommy's womb. That's why we swaddle the baby so snug, Evan Asada Burrito style. And when we open him up, we're exposing him and creating a sense of vulnerability, a feeling of insecurity.

And so Evan screams like no other moment in the day.
But as I'm cleaning him up, there's not a single second that I consider not going through the process of wiping up the mess. Not for a moment do I think it'd be better for Evan if I'd just close up the diaper again just so that he doesn't have to cry and feel insecure or vulnerable. No stinkin' way.
In my mind, as a father, it is without hesitation my desire to bring him through the process of getting him cleaned up. I know, without a second guess, it'll be good for him, and he will be glad he went through it.

God, our Father, is Good. And I know that. I've always known that.
But now, I think I feel it and understand it a little deeper.
"Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father?" Hebrews 12:7
