This is a good discussion. I am learning even while reading the comments. But Prof. Bock 'Kevin' does bring up a point in 1 Corinthians when Paul calls the gospel " the message of the cross " or " the word of the cross". He then goes on to say how it ( the message of the cross) trips up or offends both Jews and Greeks. Isn't Paul saying that the center of the gospel is the crucifixion of Christ? What about in Galatians where Paul says He only boasts in the cross?
Another question....a hypothetical one..... If Jesus died only to pay the penalty for sin and not bring us into a relationship with God would the cross be meaningless or empty?
Are there any books that deal with this issue in terms of transaction or relationship in terms of the gospel. Thanks.
