This is from an article titled Authentic Spirituality The whole article is worth reading , it's a bit long - here's a few paragraphs:
I think we do this because deep in our hearts we're trying to sell Jesus to the public. We attempt to make Him out to be more than He is in an effort to spark interest. We present "life with Jesus" as though it's a continuous mountain-top experience that comes with batteries included and a life-time guarantee. If this isn't your personal experience with Him, something is wrong with your spirituality. Sadly, the result of this pattern of exaggeration is that people chase a carrot that is always just out of reach and then become depressed and disillusioned.
Let me be the first to say that the reason you can't find the peace and joy and freedom that you've heard about is because it doesn't exist. At least not in the way it's been presented. The Christian life as advertised to you is a lie! The promises and claims that were made to you about Jesus were nothing but a list of sales tactics to close the deal. After all, who would reject eternal happiness and contentment? Who in their right mind would walk away from a Jesus who could make all their problems go away overnight? Who would say no to instantaneous freedom and victory? Especially when it's as easy as 1, 2, 3. Rattle off a quick sinner's prayer and you're on your way to a life of constant adventure and roller-coaster spirituality.
I think there is something to be said for the way Jesus presented Himself 2000 years ago. He rode into the city on the back of an ass. Now that resonates with my life! I get this real and raw picture in my mind, "Life on an Ass," and it rings true. Maybe it's not a popular concept with the Christian world, but the fact is, life is humdrum. There are "up" days and there are "down." There are times of purpose and times of purposelessness. There are extended times when there is clear direction and you know where you're going and then there are times when you just sit and stare at the walls and go nowhere. Life with Jesus is not filled with a continuous vibration of exhilaration and adventure. Scripture never promised that to us.
