This is a far more stunning article from him, that might be more his “creation” (pun intended):
Evolutionists are assuming that the seed sizes we observe in the present were the same in the past. It is quite possible that some or all of the plants with smaller seeds had yet to differentiate into the species we observe today. The jewel orchids, for example, might not have branched from the originally created orchid kind at the point Jesus made his statement.
If speciation is rapid, then evolutionists cannot make uniformitarian assumptions. Without these assumptions, evolutionists’ attempts to mock the Scripture lack foundation because what we observe today may not be what existed in the past.
I would just say (quoting from my book):
“The mustard seed is the smallest seed on earth” (Mark 4:31) is a statement with similar contextual bounds. Jesus is correct, in his context. Broadening the context, however, we find that orchid seeds are smaller, but Jesus is not in error.
