Thank you ive been thinking about doing that just never knew how to go about it XD
We are the salt of the earth
God doesn't want us to cut ourselves off from society, we're to be scattered in different places to talk the gospel to people. Saying that, yes you may see and hear certain things which could possibly decencitse you in certain ways, but just ask God to guard your heart and pray you won't be made supseptible to things. It's not a great job, but hopefully you can use that position to talk to people, and even if you don't talk to people, other's around you may notice something different about you and want to know what you have that they don't.
By following christ you'll be displaying the fruits of the spirit, while your setting may be the opposite lol. But you'll stand out, it is good for there to be light in the dark
!!
God can use people in any position.
I heard of this lady who would actually go into lapdancing clubs and bring people to christ (she's probably been around that scenario to be able to reach people in that way), but yea.
Keep asking God for guidance, and when you move on you'll find you'll be able to talk and minister to a greater range of people due to your bar experience!
