Trouble indicates better things to come.
“At that time shall Michael stand up, the great prince which standeth for the children of thy people; and there shall be a time of trouble, such as never was since there was a nation even to that same time; and at that time thy people shall be delivered, every one that shall be found written in the book.” [Daniel 12:1.]
Jesus stops his ministry in the heavenly sanctuary on our behalf and in His warrior name comes again to stop the violence and misery that man of sin have brought about. The time of probation is over. Everyone that has chosen His side will joyfully receive their salvation.
John 3:17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
