This precious promise

"His divine power has given us everything we need for life and godliness through our knowledge of him who called us by his own glory and goodness. Through these he has given us his very great and precious promises.... For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ.... Therefore, my brothers, be all the more eager to make your calling and election sure. For if you do these things, you will never fall" - 2 Peter 1:3-4,8,10
