In one extraordinary verse Peter brings together salvation, truth, holiness and love.
Even if there were not hundreds of other examples in scripture this one verse puts paid to the absurdity that truth and love are somehow alternatives, that we can be in favour of one but not the other.
To separate them is like separating breathing from the beating of the heart. The absence of either stops the other and brings death.
In holiness God brings salvation through Jesus the truth, overflowing in love to every person on earth, and as we respond to that love we cease to be what we were and become something new.
Yet Peter writes this letter because there is so much pressure to conform, and so much behaviour which is what the recipients had been, behaviour like those around them in their culture, the absence of love, competition, no grace, no hope.
There is too much of what they were, too little of what God in Christ has made them.
