What those who strive to do so seem to overlook is that the Gospel of Christ is neither a sideshow nor a debate. The Gospel was not given to dazzle the senses or stimulate the intellect. The Gospel was given to redeem souls, change hearts, and change lives. In doing so, it may very well excite our emotions and thrill our minds, but that is not its main goal or function.
We should never try to argue or dazzle someone to Christ. Doing so cheapens the Gospel. It also runs the risk of wooing someone to our eloquence or talent rather than the Gospel. That is why we see some people "fall away" from the faith. They were not drawn to Christ, but to a program; when they saw a more beguiling program, they were drawn away.
This is why it is incumbent upon us to preach the Gospel simply and stand on it firmly. Christ Jesus said in John 12:32 that if He be lifted up, He would draw all men to Himself. Therein lies our mission. All we need to do is lift up Jesus Christ and allow Him to draw men to Himself.
