Everything Is For The Good (Emunat HaShem).

After all, the book of Isaiah has more than one chapter. When we go to chapter 49, we see a couple of things. First, Isaiah the prophet that speaks in the name of God talks to all of those Jews that are suffering to the point where they feel like God forgot them. Like God has disowned them. Even though they observe the commandments, even though they've stayed loyal to him because the end of days is difficult. As says in Kohelet, there's no such thing as a person that doesn't have difficulties. Everyone has difficulties. You just have to find a way to enjoy and be happy through this life despite the difficulties. That's in essence the purpose of Kohelet, Ecclesiastes in English.
