In 1 Corinthians 15:39 we are told that “all flesh is not the same flesh, but there is one kind of flesh of men, another flesh of beast, another of fish and another of birds.” Early scientist found that all flesh contained a basic substance called protoplasm. They jumped to the conclusion that all protoplasm was the same therefore all cells were the same. But according to the findings of modern science, Paul was right. Parke Davis has produced a reagent they call “anti-human precipitin.” This is used in the scientific branches of Law Enforcement Agencies to help in forensic investigations. The need to distinguish human flesh from animal flesh confirmed Paul’s statement. The Forensic scientist is now able to show the difference between one flesh, and all other kinds. They solve crimes and prove the guilt or innocence of those charged with them. How did Paul know this, when the scientists of a hundred years ago got it so wrong?
Why did Paul say there is a difference in the flesh of humans, of beasts and birds? He was arguing with those who claimed there was no resurrection. They said you cannot raise a body from the grave once it is dust again. He describes creation, and the way things are made, to prove it can. You cannot say, “Since I cannot understand it, or I cannot do it, it cannot be done. That is a foolish argument. Much of scripture is explaining things we do not understand. So there is no surprise when God mentions something only he could know.
