Trouble is being outside of the Will of our Creator: it also comes upon those that have "rejected GOD." Trouble test one's mettle to see their stance. Trouble can visit anyone - but doesn't need to stay. Trouble can come as bad-judgment from our LORD: what does that look like: just stop, look, and listen.
Trouble = to agitate mentally or spiritually. Worry, disturbed, difficulty or problems. Matt. 13:21 Trouble = pressure, oppression, affliction, distress, etc..
For the System, Trouble comes as "labor pains" - which increase in intensity: meaning it gets worse as time goes on. One that is following Christ-Jesus must be reminded that GOD is in the fires of life with us.
Tribulation is Trouble. But Blind-leaders and Fake-prophets refuse to acknowledge it, and continue to point people to the world-system. Evangelicals have also painted themselves into a corner, as they spread deception. Babes are immune to Trouble and have found a way out - Not! The Beast is the only One that has the Capture-Doctrine.
Proverbs states that it foolish to know Trouble is a head, an to continue down the path. Repent: get on the Right-path! GOD is love, but also full of correction. People are in Trouble with the Big-G and don't even realize it. Ex.20:5 "I the LORD thy GOD am a jealous GOD, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate ME."
People that worship Idols, hate the LORD. 1Sam8:5-19 shows the process of "Rejecting" the LORD - and consequences.
Prov. 28:4 They that forsake the-Law, praise the wicked.
