I am a dispensationalist. I believe the Gospel as presented in the Bible in 1 Cor. 15: Christ died for our sins according the Scriptures, with the burial proving that, and then He rose bodily from the grave, as proven by 500 witnesses. Do you believe some other gospel?
And please enlighten us. How is the "dispensational scheme," as you put it, a "denial of the work of Christ"? Christ and His glory is at the center of dispensationalism. I believe in the incarnation, virgin birth, perfect and sinless life, substitutionary atonement by the death on the cross for our sins, resurrection, and second coming of Christ. Do you believe in something different about Christ?
