The Duck-billed Platypus defies the normal rules of nature and presents a biological conundrum. The 'Platypus Challenge' presents an opportunity to examine these areas of scripture on which there are differing opinions. (To get an idea of how it works out in practice, visit a previous question of 'Once Saved; Always Saved'.)
This Platypus Challenge is looking at the timing of the rapture of the saints. Under 'Platypus' rules, each of the two participants (of opposite views) supplies up to eight verses (or short extracts) directly from the Bible without any additional comments or remarks. Each participant then furnishes a response – in the form of a rebuttal – to the opposing verses.
