The other gentleman in the debate took a "5-point" Calvinist's position, which says God ordains some to heaven and some to hell, and Christ's sacrifice was therefore limited in effect only to those who go to heaven (i.e. Limited or Particular Atonement). In other words, when Scripture says "For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life" (John 3:16) he understands the "world" and "whoever" to mean only persons God ordains to heaven without regard to any response, merit, or attribute in those persons.
Merry Christmas. :)
