Use of the word "trouble" is a very appropriate word.
Daniel 12:1 says when Michael the prince stands up that there should come a "time of trouble" to the seed of Jacob.
It isn't a coincidence we as physical Israel (Jews) and spiritual Israel (Christianity) are experiencing a time of trouble where the seed of Ishmael is up front and central in the conflict.
This is on a parallel with Adam's trouble. He was given a paradise and was made in the exact image and likeness of God and was given authority and dominion over the whole creation, but he transgressed and fell into serious trouble. However, Adam is redeemed out of both his physical and spiritual calamity. Unfortunately, there was and now is and shall yet be a significant amount of pain and sorrow that shall come out of all of this "trouble".
In all my research and investigation of this issue, the principle here is "where much is given, much is required". If we as Jews and Christians truly wish to realize all of the promised blessings, we need to pay very close attention to the principles upon which those blessings shall naturally flow and have integrity to them. If we are slothful or if we gloss over what our God expects of us, we should expect the punishments that God said He would perform if we break our covenant with Him.
Deuteronomy 31
29 For I know that after my death ye [the children of Israel] will utterly corrupt yourselves, and turn aside from the way which I have commanded you; and evil will befall you in the latter days; because ye will do evil in the sight of the LORD, to provoke him to anger through the work of your hands.
As I understand it, Ishmael has been given the role of bringing evil upon the Jews and Christians in the latter days.
Whether the people of Islam are evil or not appears to be a moot point. They are not who provoke the LORD to anger.
Some may ask what evil have we as Jews and Christians done that provoked the LORD to such anger. I am of the opinion that Michael as Adam stood up and was ordained King as the King of the Father's Kingdom, but even though Jews and Christians were to look for its coming and build it up to their own eternal salvation in Paradise, they instead refused to accept the dominion that was given to Adam and they considered him a deluded fool and rejected Him.
