For whoever lacks these qualities is blind—shortsighted [closing his spiritual eyes to the truth], having become oblivious to the fact that he was cleansed from his old sins.

Therefore, believers, be all the more diligent to make certain about His calling and choosing you [be sure that your behavior reflects and confirms your relationship with God]; for by doing these things [actively developing these virtues], you will never stumble [in your spiritual growth and will live a life that leads others away from sin];

For if God did not [even] spare angels that sinned, but threw them into hell and sent them to pits of gloom to be kept [there] for judgment;

and especially those who indulge in the corrupt passions of the sin nature, and despise authority. Presumptuous and reckless, self-willed and arrogant [creatures, despising the majesty of the Lord], they do not tremble when they revile angelic majesties,

They have eyes full of adultery, constantly looking for sin, enticing and luring away unstable souls. Having hearts trained in greed, [they are] children of a curse.

and saying, “Where is the promise of His coming [what has become of it]? For ever since the fathers fell asleep [in death], all things have continued [exactly] as they did from the beginning of creation.”

Since all these things are to be destroyed in this way, what kind of people ought you to be [in the meantime] in holy behavior [that is, in a pattern of daily life that sets you apart as a believer] and in godliness [displaying profound reverence toward our awesome God],

So, beloved, since you are looking forward to these things, be diligent and make every effort to be found by Him [at His return] spotless and blameless, in peace [that is, inwardly calm with a sense of spiritual well-being and confidence, having lived a life of obedience to Him].
