- First off, regarding humans: Adam and Eve were perfectly designed. How do we know that? Because God told them, "If you eat....., you will die." So the obverse is true....if they didn't, they would live forever. They would still be alive today. No cancer, no heart disease; a perfect immune system.
And this genetic perfection would have been passed on to their offspring. But Jehovah God is also the Source of life (Psalms 36:9);
keeping their perfection, required listening to and obeying Him. But they wilfully pulled away from Him, and disconnected themselves from their Life source.
Regarding the Earth's weather: I'm sure you know the stats: this Earth is spinning around 1000 mph at the equator, it's orbiting the Sun at 66,000 mph., and contains a huge atmospheric system. Just be glad we're not on Jupiter!!
But consider this.....
Jesus not only healed people from all ailments; he actually exhibited control over the weather (Mark 4:35-41.....
35That day when evening came, he said to his disciples, “Let us go over to the other side.”
36Leaving the crowd behind, they took him along, just as he was, in the boat. There were also other boats with him.
37A furious squall came up, and the waves broke over the boat, so that it was nearly swamped.
38Jesus was in the stern, sleeping on a cushion. The disciples woke him and said to him, “Teacher, don’t you care if we drown?”
39He got up, rebuked the wind and said to the waves,
“Quiet! Be still!” Then the wind died down and it was completely calm.
40He said to his disciples, “Why are you so afraid? Do you still have no faith?”
41They were terrified and asked each other, “Who is this?
Even the wind and the waves obey him!”)
So the Bible tells us that even the weather can be controlled, and that
would've been the permanent situation on Adam and Eve's (and offspring'') behalf. But when they chose to disobey,
that changed everything!! (Genesis 3:1-15....vs.15 is the first prophecy, about how Jehovah will rectify matters, through the Seed, Jesus).
For being perfect, it was
easy to listen to authority, to obey. So their disobedient act led to a
much deeper issue, actually questioning God's sovereignty: his right as their Father and Creator to set guidelines for them. (That command wasn't hard to follow; just avoid one tree!!) Well, they chose to join the Original Serpent (Revelation 12:9) in rebellion! And all of God's other intelligent creatures -- all the angels -- were, and are, watching this unfold.
So for 6,000 years, God has allowed mankind to rule themselves, to settle that issue of sovereignty, whether man can successfully rule himself or not, without God intervening.
And He
hasn't stepped in on man's behalf, either....that would be defeating
His side of the issue!!
So the weather is as expected, ie., left on it's own, the kind we see on other planets.
But that won't always be the case....
If you read Isaiah 11:9, it says " the Earth
will be filled with the knowledge of Jehovah" resulting in peaceful conditions Earthwide. Revelation 21:3-4, 'no more mourning or sorrow, and
death will be no more', indicates no more deadly weather!
