I Peter 3.17 Remember, it is better to suffer for doing good, if that is what God wants, than to suffer for doing wrong!
Yes, there are two kinds of suffering - the kind you endure for doing the right thing. "No good deed goes unpunished" as they say. And of course the suffering that comes from doing the wrong thing. This second one is maddening to would be good people, and leads to the kind of suffering you inflict on yourself, as well as the consequences of wrong choices.
You could say there is another kind of suffering - the kind that comes from someone else's bad actions. True. This is sometimes unexplainable, but how you respond will affect a great deal going forward, and once again, you are back to the two options: Suffer for doing good, or suffering for doing bad.
Either way there is an awful lot of suffering going on.
But when your conscience is clear, hope enters your life, and peace becomes real. Energy begins to pick up, and the future, even with it's share of suffering, is brighter.
For a wonderful look at the topic of suffering, check out all of I Peter 3, and this in chapter 4:
v12, 13 Dear friends, don’t be surprised at the fiery trials you are going through, as if something strange were happening to you. Instead, be very glad—for these trials make you partners with Christ in his suffering, so that you will have the wonderful joy of seeing his glory when it is revealed to all the world.
