Matthew 24:12

¹⁰ At that time many will fall away and will betray and hate one another,

¹¹ and many false prophets will arise and mislead many.

Because of the multiplication of wickedness, the love of most will grow cold.

¹³ But the one who perseveres to the end will be saved.

¹⁴ And this gospel of the kingdom will be preached in all the world as a testimony to all nations, and then the end will come.

Do read the surrounding verses too, because the context often says more than a single verse.
