I ONCE WAS BLIND, BUT NOW I SEE

2 Pe 1:9-10

9 For whoever lacks these qualities is blind, [spiritually] shortsighted, seeing only what is near to him, and has become oblivious [to the fact] that he was cleansed from his old sins.

10 Because of this, brethren, be all the more solicitous and eager to make sure (to ratify, to strengthen, to make steadfast) your calling and election; for if you do this, you will never stumble or fall.
