perhaps in their time. the eternal salvation of mankind is jesus christ.
but it is still a mystery why Jewish babies and children are continuing to suffer after some two thousand plus years when the Israelis are supposed to be the "chosen children of God"...
no mystery here. reason one: because there is sin, there will be suffering. i look up a few versus if you want. second: romans explains that the chosen children of god are his spiritual children from abraham, not the genetic children from abraham. that is, after the saviour's death, the nation of israel is no longer the chosen few. the chosen few are those who believe.
Forty days and forty nights of steady rainfall would extinguish a great proportion of all but the hardiest flora (maybe the coconut was spared for a reason)?
i am not sure how god did this, but it is possible for seeds to remain airborn for long periods of time. 40 days in the air is not a problem. seeds also get caught on animal fur, bird feet, etc. i don't think noah had to worry about plant life because god took care of that for him through other means.
