I think Peter has become quite familiar with the life of the Christian. After all, he was the one who denied that he even knew Jesus and he was also one of those who went to the mount of transfiguration. At this point in his life, Peter is defending the faith with his very life. From denying the Lord to dying for the Lord, Peter speaks with authority. Peter has something to say that you would do well to hear and believe. Peter knows about growing in grace. He sums up His experience with God in this way. 2 Peter 3:17-18 "Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own steadfastness. V18 But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To Him be glory both now and forever. Amen."
