So what will that day be like...when the world ends?
Matthew 24And immediately after the tribulation of those days, the sun shall be darkened and the moon shall not give her light, and the stars shall fall from heaven, and the powers of heaven shall be moved: And then shall appear the sign of the Son of man in heaven: and then shall all tribes of the earth mourn: and they shall see the Son of man coming in the clouds of heaven with much power and majesty.
 "Wheresoever"... The coming of Christ shall be sudden, and manifest to all the world, like lightning: and wheresoever he shall come, thither shall all mankind be gathered to him, as eagles are gathered about a dead body.
 "The stars"... Or flaming meteors resembling stars.
 "The sign"... The cross of Christ.
And he shall send his angels with a trumpet, and a great voice: and they shall gather together his elect from the four winds, from the farthest parts of the heavens to the utmost bounds of them...So you also, when you shall see all these things, know ye that it is nigh, even at the doors.
And what will it be like in Heaven? All wrongs will come to right, and we will all be perfectly happy because we will be with our Creator. Our bodies, made perfect, will join our souls. So that means if you are missing an arm or leg, you will have it in Heaven.
How wonderful will it be? I can only imagine.
