Will There Be Weather and Seasons on the New Earth?

I've heard many times that on the new earth that it will be nice and sunny all day everyday. No rain that will ruin your nice picnic or fishing trip. Plus no cold snowy days that cause frozen water lines or slippery roads. The truth is I hate the sound of that. I love watching thunder storms listening to the rain hit the roof and wind howling. Looking outside on the first snow fall of the winter. I have great new for people that think like me. We will have weather and all four seasons like we do now.

KJV Genesis 8:22 - While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.

How long will the earth remain?

KJV Ecclesiastes 1:4 - One generation passeth away, and another generation cometh: but the earth abideth for ever.

How can there be a new earth if the old one we live on now will last forever?

The new earth is not a different one or to say a new creation but the old one remodeled or to say restored. To help make this a little easier to understand . When we accept Jesus as our savior we become a new creature.

KJV 2 Corinthians 5:17 - Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.

When we get saved we don't become a different creation, but remodeled just as the new earth is not a different earth, but the old one remodeled.

How can there be night when it says there is no moon or sun?

First it doesn't say there is no sun or moon.

KJV Revelation 21:23 - And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.

What it says there is no need for them at the city of New Jerusalem. The sun and moon will still exist just Gods light will shine brighter. Where it will cancel out the light for the sun or moon. Just like today we can see the moon during the day, but the sun is much brighter that we don't notice the moons light. So the new earth will still have night.

As we can see that it will be very similar to what we experience today. We just wont be hurt by it.
