2 Peter 1:9-15

For he that lacketh these things is blind, seeing only what is near, having forgotten the cleansing from his old sins. Wherefore, brethren, give the more diligence to make your calling and election sure: for if ye do these things, ye shall never stumble: for thus shall be richly supplied unto you the entrance into the eternal kingdom of our Lord and Saviour Jesus Christ. 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. And I think it right, as long as I am in this tabernacle, to stir you up by putting you in remembrance; knowing that the putting off of my tabernacle cometh swiftly, even as our Lord Jesus Christ signified unto me. Yea, I will give diligence that at every time ye may be able after my decease to call these things to remembrance.
