He has FINISHED providing all things that we need for life and godliness through the knowledge of Him who called us out of His own glory and goodness.
Through these great and precious promises (all from His own finished work) we can partake of His divine nature and escape the corruption that is in the world through lusts.
When we properly understand what He has FINISHED -
We will GIVE ALL DILIGENCE to add to our faith: Virtue, Knowledge, Self Control, Perserverance, Godliness, Brotherly Kindness and Love.
Our REST should look like GIVING ALL DILIGENCE similar to Paul's own rest. Paul was so confident that Christ was able to keep Him from falling and to present him without spot or wrinkle that he beat his body and made it his slave lest after having preached REST to others he himself would be rejected.
We are admonished to GIVE ALL DILIGENCE to enter this rest, lest any should fall by following the example of those who failed to enter because of unbelief and disobedience.
