"With minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revealed at his coming. As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all you do" (1 Peter 1:13-15)
Peter has just opened his letter telling believers in Christ of the wonder and scope of their salvation. Now he calls them to align their minds with their new gospel centred identity. They are recipients of such wonderful grace and provision. Indeed what they have in Christ is something that angelic beings marvel at, something that the prophets of old longed to see. Therefore, they are to prepare their minds for action- what kind of action?
Well, Peter says they are to set their minds on becoming holy, just as God is. Far from their salvation, the grace showed to them, being a catalyst for apathy and laziness, instead it is seen by Peter as reason to pursue holiness, to pursue godliness. The saving grace of God in Christ has opened a door to new possibilities and so Peter says discipline your minds, prepare them for action- pursue holiness. What is the state of your mind, are you prepared? God has done so much for us- let us live into what he has already won.
