"9 But resist him, firm in your faith, knowing that the same experiences of suffering are being accomplished by your brethren who are in the world. 10 After you have suffered for a little while, the God of all grace, who called you to His eternal glory in Christ, will Himself perfect,confirm, strengthen and establish you. 11 To Him be dominion forever and ever. Amen. 12 Through Silvanus, our faithful brother (for so I regard him), I have written to you briefly, exhorting and testifying that this is the true grace of God. Stand firm in it! 13 She who is in Babylon, chosen together with you, sends you greetings, and so does my son, Mark. 14 Greet one another with a kiss of love. Peace be to you all who are in Christ." - 1 Peter 5:9-14 NASB
And here we are at the end of 1 Peter. I started this blog in 2014, and though I had some large gaps in writing, I have been looking at mainly this book the entire time. It's cool for it to be coming to a close and I am excited to delve deep into a new one.
The "him" in verse 9 is Satan, as verse 8 was just talking about our adversary the devil. We are to resist the devil, and not allow him power over us. We are to not let him shake our faith. We can feel alone, and like we are the only ones struggling, but Peter says here that our brethren, other believers, are experiencing the same struggles.
After we struggle for a little while, Christ will work in us. He will perfect us. I believe that work begins the minute we surrender our life to Christ. He slowly makes us more and more like Him, until He calls us home to be with Him and the process is completed. He will also confirm, strengthen and establish us while we yet live. He has our back. He makes us better than we can be by ourselves. Do not lose heart or faith because you are attacked by Satan, know that God is working within you.
The last few verses here are Peter's closing personal remarks to specific people, and that's 1st Peter.
