2 Peter 1:12-15 ASV

12 Wherefore I shall be ready always to put you in remembrance of these things, though ye know them, and are established in the truth which is with [you].
13 And I think it right, as long as I am in this tabernacle, to stir you up by putting you in remembrance;
14 knowing that the putting off of my tabernacle cometh swiftly, even as our Lord Jesus Christ signified unto me.
15 Yea, I will give diligence that at every time ye may be able after my decease to call these things to remembrance.
