A terrible disease infects many Christians by believing life is easy and God grants everyone (with enough faith, that is) a Lexus, ice cream, and a pony. When life gets tough people hide the pain and frustration created by the paradox of what they think the Christian life should be-versus the reality they experience-by transforming into Tony the Tiger, where everything is grrrrreat! But everyone needs help sometimes. A simple, but difficult, cure comes from a stiff shot of reality - God is not a genie granting wishes, life is hard, and you may not get a pony.
If youre not resting, its time to take a good look at the letter to the Hebrews, as Paul provides warning after warning about the minefield you must pass through. Paul motivates the troops to not abandon what they know to be true, and stay in the game, even when (not if) adversity strikes.
