If you are going to spend considerable time critiquing the bible I recommend you make at least a minimal effort to understand it first. Almost every claim you make or question you ask is based on an incorrect understanding of scripture. This would be understandable if you were discussing complex theological issues but your points have been simplistic and easy to clear up. If you are not willing to spend time with a few commentaries or researching cultural language use I have to conclude your efforts to critique the bible are just manifestations of your resentment for it. You show no signs of sincerely desiring knowledge or any efforts to allow for simple harmonization. It took a whole three minutes to find the scholarly consensus concerning this issue. Why didn't you do this your self? The body we receive after we are raised from the dead is a different kind of body. Incorruptible, perfect, and eternal. It will not be flesh as we now know it to be. This is the body that Christ had after resurrection.
Clarke's Commentary on the Bible
Flesh and blood cannot inherit the kingdom - This is a Hebrew periphrasis for man, and man in his present state of infirmity and decay. Man, in his present state, cannot inherit the kingdom of God; his nature is not suited to that place; he could not, in his present weak state, endure an exceeding great and eternal weight of glory. Therefore, it is necessary that he should die, or be changed; that he should have a celestial body suited to the celestial state. The apostle is certainly not speaking of flesh and blood in a moral sense, to signify corruption of mind and heart; but in a natural sense; as such, flesh and blood cannot inherit glory, for the reasons already assigned
Here is another:
Geneva Study Bible
{28} Now this I say, brethren, that {c} flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
(28) The conclusion: we cannot be partakers of the glory of God unless we put off all that gross and filthy nature of our bodies subject to corruption, that the same body may be adorned with incorruptible glory.
(c) Flesh and blood are taken here for a living body, which cannot attain to incorruption, unless it puts off corruption.
1 Corinthians 15:50 I declare to you, brothers, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable.
As is obvious actually allowing for cultural language use, it is easily seen what was meant. That our corrupted mortal flesh cannot exist with an absolutely perfect God. Our incorruptible new bodies won't be what we know of today. They are described as incorruptible and perfect and that body can live with God.
That is the type of body Christ had when he was resurrected. It is not flesh and blood as we know it.
There are at least seven accepted commentaries at that site from respected theologians and they all point out the same solution to you simplistic challenge. Why don't you try and find these answers yourself. I do not have the time or interest in clearing up every simplistic inaccurate counter point that you can invent. Reading back over this it is maybe a bit harsh but it gets old continuously clearing up inaccurate views on scripture used as counter claims. The discussion never advances
