2 Peter 1
5 But also for this very reason, giving all diligence, add to your faith virtue, to virtue knowledge,
6 to knowledge self-control, to self-control perseverance, to perseverance godliness,
7 to godliness brotherly kindness, and to brotherly kindness love.
8 For if these things are yours and abound, you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ.
9 For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins.

10 Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble; 11 for so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ.

and again in 2 Peter 3

14 Therefore, beloved, looking forward to these things, be diligent to be found by Him in peace, without spot and blameless;

being ever more diligent in moving towards an assurance of the Lord's calling for me in my life and being found in Him, pure and blameless. :)
