1 Peter 4

1 Therefore, since Christ suffered for us in the flesh, arm yourselves also with the same mind, for he who has suffered in the flesh has ceased from sin

1-2 Since Jesus went through everything you're going through and more, learn to think like him. Think of your sufferings as a weaning from that old sinful habit of always expecting to get your own way. Then you'll be able to live out your days free to pursue what God wants instead of being tyrannized by what you want. The Message

I think the message version explains that verse so clearly. Suffering weans us from having to get our own way.
