Obfuscating the Gospel through a sensationalized vision of Dispensationalist fantasy does just that, it obfuscates the Gospel, or worse covers the Gospel completely with a dark cloud completely hiding it from view.
My chief issues with [pop]-Dispensationalism, actually, aren't merely quibbles with esoteric eschatological concepts such as the Millennium or the rapture (though, I do have my quibbles with those too), it's instead the broader practical, ethical and theological ramifications the relationship between Church and Israel in Classic Dispensationalism I certainly find troubling from an ecclesiological, soteriological and eschatological perspective; but rather I find most troubling is what it ultimately says about God and Jesus Christ.
Do we believe in a God who, as revealed in Jesus, is so passionately in love with His world and we human beings that He will go to the incredible depths to condescend to assume human nature, live among us, suffer and die a shameful death to rise and liberate us from the power of sin, death and hell--all because He loves us so much that He desires to save us...only to eventually say, "I'm done playing around, it's too late, turn or burn."?
In which case, even if lots of people became Christians after reading the Left Behind books, it's rather disconcerting that their Christianity is at the expense of the Gospel, and that a view of God has been presented that clouds a true vision of God as presented in the Gospel.
That disturbs me and I find that unsettling as a Christian.
“If we truly believe that Christ is our Savior…then we have a God of love, and to see God in faith is to look upon His friendly heart.” - Martin Luther (from Luther, the movie)
"What is a merciful heart? It is a heart on fire for the whole of creation, for humanity, for the birds, for the animals, for demons, and for all that exists. By the recollection of them the eyes of a merciful person pour forth tears in abundance. By the strong and vehement mercy that grips such a person’s heart, and by such great compassion, the heart is humbled and one cannot bear to hear or to see any injury or slight sorrow in any in creation. For this reason, such a person offers up tearful prayer continually even for irrational beasts, for the enemies of the truth, and for those who harm her or him, that they be protected and receive mercy. And in like manner such a person prays for the family of reptiles because of the great compassion that burns without measure in a heart that is in the likeness of God." - St. Isaac the Syrian
"But rather, love your enemies and do good to them, and lend expecting nothing back; then your reward will be great and you will be children of the Most High, for He Himself is kind to the ungrateful and the wicked. Be merciful, just as your Father is merciful." - Luke 6:35-36
