Observation: Peter begins the instruction portion of this letter discussing the ever-improving character traits believers should strive to keep, and says it is proper for him to remind them of these traits as long as he is still alive ... for he will die exactly as Jesus told him he would. This could be just one of those offhanded comments like "we all know we'll die someday" types of comments, however we know the facts are different for Peter. He knows for certain - told to his face by the Messiah himself - that he will be crucified by the Romans. Peter knows that time is nearing, as suppression of Christians is spreading, so he isn't making an offhanded comment ... he is speaking as one for whom the Lord himself has revealed his fate, that fate in near, that fate is certain, and that fate is scarry.
Application: My fate is not revealed to me, and any discussion I have about my death is of the offhanded "I'll die someday" variety. However, I have become aware that "someday" now seems soon. I have friends who have died, and I hear of people younger than I who die regularly. Even my best-case scenario of how long my family genetics likely would have me live bring my end within sight ... I have had 'seasons' of my life that have lasted about the same number of years as there are between my 'now' and 'then.'
I'll die someday, and my greatest concern is that I am not doing the work of the Lord that I am supposed to be doing. Unlike Peter, I'm not using my time in this "bodily tent" to do all I could for the kingdom of God. Sure, I do some, but that is far from enough.
Peter reminds me today that there is still time. My tent is still standing (even as I dreamed last night about camping!). I have time to practice faith, goodness, knowledge, self-control, endurance, godliness, brother affection, and love ... and then to act in accordance with all those toward others around me.
Prayer: Lord, the harvest field is before me. Send me. May I do better and better each day in following your ways, so that I may serve you all the rest of my days, no matter how long that may be. Amen.
