"All this I have told you so that you will not fall away."
I wrote this in response to today's post in an excellent series by 
We should work hard to make sure all Christians thoroughly get the fact that things are going to get worse and worse for them. Most have lived their lives in the comfortable majority. This is not going to continue. I suspect that the great Falling Away that Paul talks about is from unprepared Christians who "can't stand the heat" in the last days.
2 Thessalonians 2:3
Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition.
Revelation 13:7
Then the beast was permitted to wage war against the saints and conquer them, and it was given authority over every tribe and people and tongue and nation.
Revelation 14:12
Here is a call for the endurance of the saints who keep the commandments of God and the faith of Jesus.
Daniel 7:24-25
And he shall speak great words against the most High, and shall wear out the saints of the most High,
and think to change times and laws:
and they shall be given into his hand
until a time and times and the dividing of time.
Revelation 13:7, 9-10
It was granted to him to
make war with the saints
and to overcome them…
He who has an ear, let him hear.
If anyone is to go into captivity,
into captivity he will go.
If anyone is to be killed with the sword,
with the sword he will be killed.
This calls for patient endurance
and faithfulness on the part of the saints.
Revelation 6:9-11
When he opened the fifth seal, I saw under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained. They called out in a loud voice, "How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood?" Then each of them was given a white robe, and they were told to wait a little longer, until the full number of their fellow servants, their brothers and sisters, were killed just as they had been.
Matthew 24:9-13
Then you will be handed over
to be persecuted and put to death,
and you will be hated by all nations because of me.
At that time many will turn away from the faith and will betray and hate each other, and many false prophets will appear and deceive many people.
Because of the increase of wickedness,
the love of most will grow cold,
but the one who stands firm to the end
will be saved.
John 16:1-4
All this I have told you
so that you will not fall away.
They will put you out of the synagogue; in fact,
the time is coming when anyone who kills you
will think they are offering a service to God.
They will do such things because they have not known the Father or me.
I have told you this, so that when their time comes you will remember that I warned you about them.
It's not going to be pretty, but we will be much stronger if we are realistic about what to expect.
