One way the Enemy fights the Gospel is by keeping people from feeling their pain. Mental and physical anguish both stimulate change—by nature, we want to avoid pain. As much as we may dislike it, pain plays a very important, God-given role in our lives. If the Enemy can get us to numb our pain without debilitating side-effects, then we're less likely to repent of the lifestyle that is causing the pain.
In reality, money is just a tool of the Adversary. His goal is to frustrate the plan of God and destroy the lost souls which God cares so much about. In the Book of Revelation we find that drugs are one of the main tools of Mystery Babylon, the religious/economic powerhouse of the Kingdom of Darkness. Regarding the future, an angel told the prophet John:
"'So will Babylon the great city be thrown down with violence, and will be found no more.... for your merchants were the great ones of the earth, and all nations were deceived by your sorcery'" (Rev. 18:21-23).
That last word—translated into English as 'sorcery'—is the Greek 'pharmakeia.' It means "drugs." In context, the angel must be referring to mind-altering drugs used to trick people into going along with the desires of Babylon.
In the Spirit, I perceive that the current surge in psychiatric drug prescriptions will lead to the development of a numbing Rx cocktail which will be liberally provided to nearly everyone living in the Babylonian system.
I caution you not to go along with the system. It's normal to be temporarily upset when things go wrong, and it's normal to mourn when we lose someone, but long-term depression is abnormal for Christians. The life of a disciple of Messiah is marked by peace and joy, not inner turmoil and anxiety. If you find yourself perpetually lacking peace and joy, the real solution is to ask your Heavenly Father to point out which area of your life is subject to sin. He will, when asked by someone who is genuinely ready to change. Then it's simply a matter of tweaking your lifestyle so that it conforms fully to the will of Adonai—and don't forget to praise him as you do so!
