What order should the seven statements from the cross be studied in?

Les teaches that the seven statements from the cross are to be taken in their chronological order in time, not according to their order in Scripture. He has the class turn to Luke chapter 23 and warns that they will be jumping back and forth among the Gospel accounts, hoping the sequence unfolds as they do so. He explains this is what you have to do with the Gospels. Many people assume the feeding of the 5,000 in one Gospel is the same feeding of 5,000 in another, but that is not necessarily true; each account can have different circumstances and details. That does not mean the writers conflict. One may be talking about one event and another about a different event. John says all of Christ's miracles were not recorded, only a small portion; if all were written down, the world could not contain it. So only highlights are given. As you study the Gospels, keep in mind there is no contradiction. One writer gives an account of this event, another of that. Sometimes they record the same event, and the details show it. If the details do not fit, they are reporting something that was not at the identical same time.
