Summary of passage: Peter (the most widely-accepted author of this book) tells the readers of this letter that God’s divine power has given us everything we need for life and godliness through our knowledge of Him. By His great glory and goodness He has given us great and precious promises so that we can be with Him (the promise of sanctification and eternal life).
Therefore, we must strengthen our faith, goodness, knowledge, self-control, perseverance, godliness, brotherly kindness, and love in this world in order to be effective and productive in knowing Jesus. If we do these things (our calling and election), we will never fall and we will be welcomed into the eternal kingdom.
Peter promises to remind them of these things always as he is close to death. He was an eyewitness to Christ’s majesty and stood on the mount as God himself declared Jesus as His son. Plus, the words of the prophets confirm Christ as their words were from God.
3) Eternal life given to us through the sacrifice of Jesus Christ
4) A Christian must add to his/her faith: goodness, knowledge, self-control, perseverance, godliness, brotherly kindness and love. If you possess these qualities you will be effective and productive in knowing Him. Make your calling and election sure (verse 10) by doing the above.
5a) Peter was an eyewitness to Jesus and heard God declare that Jesus was His son. And the prophets confirmed the truth who spoke from God’s will not their own (i.e. spoke God’s words, given to them by God).
b) Personal Question. My answer: By the way I live my life. When I speak, I am sure. I hope it radiates from me and my belief shines through. And my knowledge of Bible and Scripture (which needs to be strengthened).
Conclusions: I need to work on all of the aforementioned truths and callings of a Christian’s life: faith, goodness, knowledge, self-control, perseverance, godliness, kindness, and love. I think I’m weak in all aspects (which probably explains my falls). Great reminder of what we should be doing in this world.
