Matthew Henry on 1 Peter 1:13-23
Here the apostle begins his exhortations to those whose glorious state he had before described, thereby instructing us that Christianity is a doctrine according to godliness, designed to make us not only wiser, but better.
I. He exhorts them to sobriety and holiness.
1. Wherefore gird up the loins of your mind, etc., Pe1 1:13. As if he had said, "Wherefore, since you are so honoured and distinguished, as above, Gird up the loins of your mind. You have a journey to go, a race to run, a warfare to accomplish, and a great work to do; as the traveller, the racer, the warrior, and the labourer, gather in, and gird up, their long and loose garments, that they may be more ready, prompt, and expedit…

John Gill on 1 Peter 1:16

be ye holy, for I am holy: an argument the apostle knew must have weight with these persons, who were chiefly Jews, scattered abroad among the Gentiles, and had a value for the Scriptures of truth; and therefore, as the argument for holiness of life, from the nature and perfections of God, is strong, it must receive additional strength from this being the declared will of God, even their sanctification on this account; and though holiness, equal to God, is never to be attained to by a creature, yet so far as it is capable of it, it is desirable, because agreeable both to the nature and will of God, by all such who are truly his children, who lo…
