technically that is from the teaching of the second coming of Christ . certainly we dont need to jump ship but grace will sustain us
He that endures the Great Tribulation until its end will be raptured, saved.
7 For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.
8 All these are the beginning of sorrows.
9 Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake.
10 And then shall many be offended, and shall betray one another, and shall hate one another.
11 And many false prophets shall rise, and shall deceive many.
12 And because iniquity shall abound, the love of many shall wax cold.
13
But he that shall endure unto the end, the same shall be saved. (Matt. 24:7-13 KJV)
12
Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16
And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
(Rev. 14:12-16 KJV)
