John 16 (TLV) ³³ These things I have spoken to you, so that in Me you may have shalom. In the world you will have trouble, but take heart! I have overcome the world!” source

In this world you will have trouble. Period. End of the sentence. You will. I will. I do. You do.  And yet. Take heart.

Why? Because He has overcome the world!

Notice it is past tense.
Not I will overcome.
Not I may overcome.

Nope! I have He said! 

Perhaps we can look our troubles squarely in the face today and say Perhaps I can’t overcome you.  
But that’s okay. Because He already has!
