Moreover, suffering is caused by our emotional state. We feel suffering because we feel like we are worse off than our previous condition/circumstances; however, suffering does not always come after sinful acts. It is all relative, based off primarily emotional distress. This is why Jesus Christ's life, death, and resurrection are simply amazing. Although he seemed as if he was suffering, he did not sin. He was the innocent lamb from which He was slain for our iniquities. Sin and suffering are usually paired together, but do not have to be.
Now, the problem of evil in our lives is quite tragic. We live in a broken world. God intended it to be broken, and He is the supreme God. However, the problem of evil is extremely small in the glimpse of eternity. Our Lord did not promise good to all mankind because it will not happen in this lifetime. Our purpose in this present world is not to enjoy it and then hope for the best. Our purpose is to find the truth, our reason for living, and that is to submit our lives in Jesus Name, and to live for Him until He comes again.
You see, my friend, even though people's circumstances are hard - financial struggles, poor, homeless, abused, addicted - the common ground that they can live on is life. Why didn't they die from their addiction? Why didn't they die from their suicide attempt? You see, God has spared their life because there is a bigger purpose for them in this lifetime. They are still alive, breathing.
This is the same with the other spectrum of people, who are rich and famous. Deep down, they are just as broken and needy as the ones who are poor and broken. In our human state, we all need a Savior, and that is Jesus. No one is exempt, no matter what situation they are in.
