Knowing the Gospel - a New 4 Spiritual Laws?

I read an interview today at ChristianityToday.com with an author named James Choang.  He has developed a new way of expressing the gospel, something he calls "the Big Picture."  It focuses on four phases: 1) designed for good, 2) damaged by evil, 3) restored for better, and 4) sent together to heal.  He design is meant to replace the infamous Four Spiritual Laws with a method of seeing the gospel as not being so individualistic, but rather more corporate; something which definitely would be more understandable and attractive to today's teens, 20 & 30 Somethings.  

I am not going to attempt to fully critique his "Big Picture" method, but want to highlight one thing I picked up in the interview.  When asked how the Big Picture considers the atonement (i.e. Jesus dying on the cross, as our substitute, to appease God's just wrath upon us due to our sin), he seems to stray from an orthodox and biblical understanding of atonement.  The atonement is always in the context of the perfect God-Man Jesus shedding his blood (dying) for sinful people. Christ's death is repeatedly correlated to the Old Testament sacrifices, most specifically detailed in Hebrews 9:11-28.  The idea that we are "vampire Christians" (a quote from Dallas Willard which he supports) goes against what is clearly taught and emphasized in Scripture.  

So why is this important to you?  Because it highlights the absolute importance of knowing what the gospel actually is.  We can (and should) use many different illustrations and analogies of the gospel, but we cannot change the meaning of the gospel.  Paul gives this clear definition in 1 Corinthians 15:1-4: "Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas..."
