Earth vs world...
When Jesus returns, it's the end of the 'world'. The 'god (little g) of this world' get's locked up for 1000 years. Jesus overcomes 'the world'. Love not 'the world'. etc...
The earth is what God made man from. Apparently, after the 1000 year reign, Day of the Lord, Sabbath day, day of rest or whatever else we may call it, God will destroy this one and make new. No more wars and no more thinking we can govern ourselves without our King.
2 Corinthians 4
3 But if our gospel be hid, it is hid to them that are lost:
4 In whom the
god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
John 16
33 These things I have spoken unto you, that in me ye might have peace.
In the world ye shall have tribulation: but be of good cheer;
I have overcome the world.
Matthew 24
1 And Jesus went out, and departed from the temple: and his disciples came to him for to shew him the buildings of the temple.
2 And Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down.
3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the
end of the world?
4 And Jesus answered and said unto them, Take heed that no man deceive you.
5 For many shall come in my name, saying, I am Christ; and shall deceive many.
