Do you know how to obtain holiness? 2 Peter

2 Peter 1:4 (NASBStr)

For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of the divine nature, having escaped the corruption that is in the world by lust.

There is some debate about how we can be like God; and, for some, BE God.  During the Greek world, in which Peter was writing, there was much talk about how to be like the gods.   They, the philosophers of the day, thought that "matter" was evil and since we were in the human body we had to transcend the body.   Through knowledge and intellectual thought, to them, we could become like God.  Peter, here in this passage is about to tell the Christians of the day that their bodies are NOT evil and, in fact, ought to be the containers of holiness.   He is telling us that we CAN BE partakers of God's holiness.   He tells us that we can be holy in this body, not by our own efforts, but by faith in God's promises.  It is by those promises and our belief in them that allows us to be partakers of God's holiness.  Our bodies are destined for corruption.  The flesh wants us to succumb to the temptations of life and of Satan.  But, God saved us from that fate and gave us His promises that will not only save us, will make us holy for Him, as well.   We do not get saved by our own efforts and we do not get holy by our own efforts.  It is by faith in God's promises that we can attain salvation and the holiness demanded by God that comes with that salvation.
