Charles Spurgeon Commentary 2 Peter 1:8

"For if these things are yours and abound, they make you to be not idle nor unfruitful unto the knowledge of our Lord Jesus Christ." — 2 Peter 1:8 (ASV)

For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.

I am sure you do not wish to be barren; I cannot imagine that any of you will be content to be unfruitful; so seek after all these virtues, and may God help you to give diligence to the attainment of them.
