Ok, I shot too much from the hip on that last post. The 1 Cor Pauline discussion has been a topic I rehashed some years ago. I repeated a position I held but now question.
In short Paul seems to be arguing about different types of flesh: man, bird, fish, and finally the ultimate type of flesh is an incorruptible type that Christians get to go to heaven with. The lines about 'sown natural raised spiritual' have been most often interpreted to mean 'spirit' but it doesn't really flow from the argument. The word can simply mean of divine or heavenly nature. Similarly, the "flesh and blood cannot enter heaven" may have had a nuanced meaning, merely insisting the usual corruptible human form cannot go. If this is correct, Paul seems to be saying they will have incorruptible glorious but yet physical bodies after a yet future resurrection.
However at Philippians 1:21 For to me, to live is Christ, and to die is gain. 22 But if I live on in the flesh, this will mean fruit from my labor; yet what I shall choose I 4cannot tell. 23 5For I am hard-pressed between the two, having a ldesire to depart and be with Christ, which is mfar better. 24 Nevertheless to remain in the flesh is more needful for you.
He seems to be rather forcefully suggesting if he was to die he would depart and be with Christ separated from his flesh.
Maybe this all illustrates the confusion.
