There is no way that the church can outdo secular entertainment given the latter's financial resources and greater talent pool. So-called Christian rock, heavy metal, and country are generally imitations of the secular genres, and not good ones at that (or so I have been told). Movies based on the "Left Behind" series seem like low grade knockoffs of better crafted secular "end of the world" movies like "Independence Day." Why would a consumer (other than an already converted Christian) spend his money on the lesser quality "Christian" product, when he can listen to or watch the better quality secular one? If the purpose of "Christian" movies and music is to spread the Gospel message among the unsaved, it will not succeed.
About nine years ago, in the suburb of Dallas where I live, the largest evangelical church in the community sponsored a group of weight lifters and stuntmen called "The Power Team," who would break cement blocks and tear apart phone books while saying Bible verses or warning against drugs. After the presentation, there was an altar call, with dozens of children, teenagers, and adults responding, and many later being baptized. However, after a few months, almost none of the converts were on the rolls of church members.
Even if non-Calvinists are unconvinced, based on their interpretation of Scripture, of the inability of man to persuade the unbeliever when the Holy Spirit has not done so, the lessons of experience should teach them that conforming to the styles and fads of the mainstream culture has been a failure.
I have seen the Power Team on Television several times. Not my cup of tea, but hopefully some of the souls they have helped win are still going on!
