Matthew 24:4-8 (AMP) Jesus answered them, Be careful that no one misleads you [deceiving you and leading you into error]. For many will come in (on the strength of) My name [appropriating the name which belongs to Me], saying, I am the Christ (the Messiah), and they will lead many astray. And you will hear of wars and rumors of wars; see that you are not frightened or troubled, for this must take place, but the end is not yet. For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in place after place; All this is but the beginning [the early pains] of the birth pangs [of the intolerable anguish].
Matthew 24:10-14 (AMP) And then many will be offended and repelled and will begin to distrust and desert [Him Whom they ought to trust and obey] and will stumble and fall away and betray one another and pursue one another with hatred. And many false prophets will rise up and deceive and lead many into error. And the love of the great body of people will grow cold because of the multiplied lawlessness and iniquity, But he who endures to the end will be saved.
And this good news of the kingdom (the Gospel) will be preached throughout the whole world as a testimony to all the nations, and then will come the end.
