2 Peter 1:11

For if these things are yours and abound, they make you to not be idle or unfruitful in the knowledge of our Lord Jesus Christ.

For he who lacks these things is blind, seeing only what is near, having forgotten the cleansing from his old sins.

Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble.

Therefore I will not be negligent to remind you of these things, though you know them and are established in the present truth.

I think it right, as long as I am in this tent, to stir you up by reminding you,

knowing that the putting off of my tent comes swiftly, even as our Lord Jesus Christ made clear to me.
