Worry - when I am unable to see Jesus in the midst of my circumstances.

"while we look, not at the things that we 'see', but at the things that we do NOT see; for the

 things that we 'see', are only temporary, but the Things that we do NOT see, are Eternal."

(2 Cor 4:18)

"I have spoken these things to you so that IN ME you might have Peace. In the world you 

have tribulation. That is no cause for fear though, because I have overcome the world!"

(Jn 16:33)

"Fixing our eyes on Jesus..."

(Heb 12:2)
