God wants to strengthen our faith, and reveal to us that we can trust Him. This would be impossible if we had no needs, no worries, no stress. 

We're going to worry in this world about many things. And as the stress of this world hits, if we're wise, we'll humble ourselves before Him, and seek His hand for help. 

God uses the stressors of this world, to reveal Himself to those who love Him. 

And through it all, His timing is always perfect. He is never late, nor is He early. He arrives PRECISELY, when He intends to.
