So are people claiming that Samson could have been muscular still because the text does not say? Would the story make any sense if he was muscular? If so, please explain why they needed to figure out the mystery to the source of his strength if he was muscular.
Raise your hand if you believe Samson could have been muscular. When I say the word "could" that means it is possible but it may not necessarily be so.
I think the story holds equal power both ways, with Sampson being "average" in size as the more likely.
But, I do hold that he could have been very muscular, with his strength still far outmatching his size, and deeds overshadowing his mortality.
It is just as miraculous either way, as no mortal could possess that amount of strength.
These feats have only been matched in modern times... and those by 300ft wrecking balls, TNT, and assault rifles.
Basically, it takes Faith to believe that the story of Sampson is true, regardless of how muscular we imagine him being.
Atheists still must say "it is either a lie, or a gross exaggeration", because the story is too fantastic for the unbeliever to accept.
