Do you know how God is using suffering in your life? 1 Peter 4-5

1 Peter 4:2 (NASBStr)

... so as to live the rest of the time in the flesh no longer for the lusts of men, but for the will of God.

Conduct follows belief.  Peter is concerned, in this book, that some of the believers who have been "dispersed abroad" would fall from the faith and succumb to the sins, again, of the flesh.   To assure they don't he tells them, in verse one of this chapter, to "arm themselves" with the same purpose and resolve of their Savior: Who put an end to sin and its rule over man but suffering.  So, Peter goes full cycle and shows them that the suffering that Christ went through ended the chain of sin over them.   So, now, they are to trust that the suffering they are now experiencing is also to have  an affect on sin; this time, to end it in their lives.   Good doctrine should always proceed great living, but good living must always follow great doctrine.   To "arm yourself" (4:1) was to set your mind with the correct resolve about suffering.   God uses suffering in our lives to direct us into His holy will.  Note in the above verse (4:2) that we are to "no longer" live in the flesh, like other men, but we are to live "for the will of God."  Note, also, what Peter says in the last verse of this chapter:

1 Peter 4:19 (NASBStr)

Therefore, those also who suffer according to the will of God shall entrust their souls to a faithful Creator in doing what is right.

It is only after we arm ourselves with the resolve that God knows what He is doing with suffering in our lives that we can entrust our souls to Him.  He is "faithful" and always "doing what is right."   That means whatever suffering I am going through, for the cause of Christ, is known by God and used by God to prepare me in my fight against sin.   Peter is very much concerned about the conduct of those who are being dispersed abroad by the suffering Rome was bringing on believers.   (cf. 1:12, 14- 15, 18, 23; 2:23; 3:3- 4, 9, 21; 4:15- 16; 5:2- 3; cf. 2:18, 20).   He wanted them to realize that suffering was within the will of God and was for the purpose of conforming us to the image of the Son of God.  We are to "arm ourselves" with that resolve and purpose and that, by faith, will enable us to live the rest of the time "no longer for the lust of men, but for the will of God."
