What did Les say about Adam's body before Adam sinned?
Adam, before he sinned, had a body identical to Christ's earthly appearance, though this is acknowledged as not provable from Scripture. Though the first man was earthy, formed from dust, before sin he was incorruptible and could have lived forever had he not fallen.
Les explains that Paul contrasts the first man, Adam, who is of the earth and earthy, with the second man, the Lord from heaven. Adam is the federal head of the human race, and Christ is the response to that head because Adam fell. Les says he cannot prove it from Scripture, but he likes to think Adam before he sinned had a body identical to Christ's in His earthly appearance. He notes that Adam before sin was incorruptible and could have lived forever had he not fallen, while Christ did not fall.
