. . . 15 but as he who called you is holy, be holy yourselves in all your conduct; 16 since it is written, “You shall be holy, for I am holy.” (1 Peter 1:15-16)
At first look this seems like a tall order, because over the centuries we have lost the definition of holy. Most people think that the word means to be morally or spiritually superior. The Hebrew word kadosh means to be separated for God’s purposes and it can apply to inanimate objects, such as the utensils of the temple. It is not an attitude but rather a purpose.
Peter is quoting from the passage on kosher eating, explaining what is clean and unclean for those separated for God’s purpose.
For I am the LORD your God; consecrate yourselves therefore, and be holy, for I am holy. You shall not defile yourselves with any swarming thing that crawls upon the earth. Lev. 11:44
Now the standard teaching in most churches is that we don’t have to eat kosher. (Fine go ahead and eat that which is not good for you.) They instead spiritualize the law saying that we are to stay away from things that are pagan or some behavior that they find repugnant such as drinking alcohol or dancing. For them it all becomes a list of “do nots.”
Peter’s point is not what to give up, but rather to find our purpose or destiny. What it is to obey our calling.
13 Therefore gird up your minds, be sober, set your hope fully upon the grace that is coming to you at the revelation of Jesus Christ. 14 As obedient children, do not be conformed to the passions of your former ignorance, 15 but as he who called you is holy, be holy yourselves in all your conduct; 16 since it is written, “You shall be holy, for I am holy.” 17 And if you invoke as Father him who judges each one impartially according to his deeds, conduct yourselves with fear throughout the time of your exile. 18 You know that you were ransomed from the futile ways inherited from your fathers, not with perishable things such as silver or gold, 19 but with the precious blood of Christ, like that of a lamb without blemish or spot. 20 He was destined before the foundation of the world but was made manifest at the end of the times for your sake. 21 Through him you have confidence in God, who raised him from the dead and gave him glory, so that your faith and hope are in God. 1Pet. 1:13-21
We are already separated, we must now find our purpose. We must find the deeds that by which we are to conduct ourselves.
What is your purpose? Mine is to sit and write theology since I have finished raising my children. However all the time I was raising them I was reading and studying knowing that this day would come somehow. I had no idea that the computer would open the world, I just kept studying because I knew it was my purpose.
Finding one’s purpose is a journey in submission to God. Whatever He has for us we must be willing to make any sacrifice to do it. A good place to start looking is in The Gifts. Find you purpose, find your holiness.
