1. Neither Noah and his family nor Lot and his family were taken out of this world, but they were protected from the evil.
Being protected from the evil does not mean you are not going to die, it means you will not succumb to the lies. God ensures this by allowing death to come swiftly:
Isa 57:
1The righteous perish,
and no one takes it to heart;
the devout are taken away,
and no one understands
that the righteous are taken away
to be spared from evil.
2Those who walk uprightly
enter into peace;
they find rest as they lie in death.
So what do we do with this:
Psalm 116:
15Precious in the sight of the Lord
is the death of his saints.
The above is what it means the elect will not fall for the strong lies (Matt 24:24)
2. The issue about one being taken and another left doesn't mean people will fly off from this earth.
A car accident, all people die but one survives; this is the meaning. Some will be protected from physical harm- those that know God. Jeremiah 24 explains this.
3. Our flight
Yes the bible talks of a flight for believers but it doesn't mean that people will fly off this earth, same thing as being caught in the air. After careful study, i realized that this means that believers don't even die but transition by immediately resurrection and indwelling other believers. That moment of transition is what is referred to as 'flight' or 'being caught together' with those that are alive. This is happening even today.
