2 Peter 1:10-12

Revised Standard Version Catholic Edition

¹⁰ Therefore, brethren, be the more zealous to confirm your call and election, for if you do this you will never fall; ¹¹ so there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ.

¹² Therefore I intend always to remind you of these things, though you know them and are established in the truth that you have.
