Bottom line: We can have hope in the midst of crisis whether it is personal, national, or global because God is in control.
Daniel 8 focuses on the time between the writing of Malachi and the ministry of Jesus. It more specifically speaks to the time of crises brought upon Israel by Antiochus Epiphanes. Daniel receives this vision from God to share with the Jews to encourage them that before things get good in Israel (i.e. the arrival of the King of Chapter 7), things are going to get bad. However, no matter how bad thing may get or how difficult a crisis may be that we face, we have hope because God is in control.
