Because
His divine power has given us everything required for life and godliness through the knowledge of him who called us by his own glory and goodness. By these he has given us very great and precious promises, so that through them you may share in the divine nature, escaping the corruption that is in the world because of evil desire. For this very reason, make every effort to supplement your faith with goodness, goodness with knowledge, knowledge with self-control, self-control with endurance, endurance with godliness, godliness with brotherly affection, and brotherly affection with love. For is you possess thsse qualities in the increasing measure, they will keep you from being useless or unfruitful in the knowledge of our Lord Jesus Christ. The person who lacks these things is blind and shortsighted and has forgotten the cleasing from his past sins. Therefore, brothers and sisters, make every effort to confirm your calling and election, BECAUSE if you do these things you will never stumble. For in this way, entry into the eternal kingdom of our Lord and Savior Jesus Christ will be richly provided to you.
2 Peter 1:3-11
