"I have told you these things, so that you may have peace. In this world you will have trouble. But take heart! I have overcome the world." ~ John 16:33 (NIV)
"In this world you will have trouble"
There it is. Right there. In Scripture. "You will have trouble." No promise of a trouble-free life. Not even 'you might have trouble'. Nope. You WILL have.
Sounds discouraging. Doesn't it?
"But take heart!" There's good news along with that trouble. Jesus overcame the world.
And because of that, we can experience peace - even through the troubles!
