2 Timothy 3:1
(1) But know this, that in the last days perilous times will come:
1 John 2:14-16
(14) I have written to you, fathers, Because you have known Him who is from the beginning.
I have written to you, young men, Because you are strong, and the word of God abides in you, And you have overcome the wicked one. (15) Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. (16) For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world.
