What period should we study about the resurrected body?

Les teaches that the period to study concerning the resurrected body is the forty days after Christ’s resurrection and before His ascension from the Mount of Olives. He points to Philippians 3:20-21, where Paul writes that our citizenship is in heaven, and we look for the Savior, the Lord Jesus Christ, who will change our vile body—prone to sin, death, and disease—to be fashioned like His glorious body. Les also notes that Abraham had this concept of resurrection when he was ready to offer Isaac, believing God would raise him. Les emphasizes that Paul lays out the resurrection clearly, and Colossians says we have already been translated into the Kingdom of Heaven. Therefore, the forty-day period is the focus for studying the resurrected body.
