There's a scene in X-Men 2 when one mutant tries to convince another mutant he is seeing something that doesn't exist. The mirage is very believable - complete with the right atmosphere, characters, voices and script. The problem is, of course, is that it's fake.
Sometimes I think the enemy uses a similar tactic against followers of Jesus. He attempts to paint a picture of doom and gloom, and he uses real characters, situations or comments to create a false reality. Unfortunately, it's all too easy to fall for his version of life rather than to look to the One who gives true hope and life.
One Bible writer described faith as "the substance of things hoped for, the evidence of things unseen." If I were to define faith I'd say it was "willfully refusing to look at the things and situations around us and opting to look at and trust God."
Or, as one band said, "when you don't understand, when you can't see His plan, when you can't trace His hand, trust His heart."
