'Earth' in the Bible

For this we declare to you on the Lord's own authority--that we who are alive and continue on earth until the Coming of the Lord, shall certainly not forestall those who shall have previously passed away.

Then we who are alive and remain [on the earth] will simultaneously be caught up (raptured) together with them [the resurrected ones] in the clouds to meet the Lord in the air, and so we will always be with the Lord!
