2Thess1:6- Since it is a righteous thing with God to repay with tribulation those who trouble you.
We call God the LORD of host because He has a host of angels that He uses in fighting battles, He is the LORD over them. He controls their activities to favour His children and to shame the devil.
For those that think spiritual warfare is a joke, Paul in the above scripture made it clear that it is a just or holy phenomenon for God to fight those that trouble you. Life is warfare and not a play-fare, you need to engage God in your warfare before your welfare can be delivered.
Those challenges in your life are writing an invitation to the God that has never retreated in a war, engage Him in prayer, praise and Holy living, then your warfare shall be accomplished.
You shall win that battle.
Father, I stop every battle(mention them by name) waging war against my life In Jesus Name.
