2 Peter 1:10-12

10Wherefore the rather, brethren, use diligence to make your calling and election sure, for doing these things ye will never fall;

11for thus shall the entrance into the everlasting kingdom of our Lord and Saviour Jesus Christ be richly furnished unto you.

12Wherefore I will be careful to put you always in mind of these things, although knowing [them] and established in the present truth.
