2 Peter 3:17-18 YLT

17 Ye, then, beloved, knowing before, take heed, lest, together with the error of the impious being led away, ye may fall from your own stedfastness,
18 and increase ye in grace, and in the knowledge of our Lord and Saviour Jesus Christ; to him [is] the glory both now, and to the day of the age! Amen.
