2 Peter & Jude: Standing Firm, Good Book Guide by Miguel Nunez and published by The Good Book Guide.
"Make every effort to confirm your calling and election," 2 Peter 1:10 tells us. "For if you do these things, you will never stumble". However well we are running now, we all need to be aware of the danger of falling away—especially in today's culture, where we are constantly bombarded by ideas contrary to the word of God. We are each responsible to hold on to the truth. The original readers of 2 Peter and Jude had come under the influence of false and immoral teachings, and these letters were written precisely to help us to stand firm in our faith.
These letters include serious warnings but also deep hope. It is through pursuing God, the one who keeps us from stumbling, and throwing ourselves on his mercy that we will make it to the end of the race. We can look forward to being presented before his glorious throne "without fault and with great joy" (Jude v 24).
