Given the vicious political environment we find ourselves in today, I share this letter of Penington's from 1667:
Letter 21 ON LOVE, MEEKNESS, AND WATCHING OVER EACH OTHER. To Friends in Amersham.Friends:-
Our life is love, and peace, and tenderness, and bearing one with another, and forgiving one another, and not laying accusations one against another; but praying one for another, and helping one another up with a tender hand, if there has been any slip or fall, and waiting till the Lord gives sense and repentance, if sense and repentance in any be wanting. Oh, wait to feel this spirit, and to be guided to walk in this spirit, that ye may enjoy the Lord in sweetness, and walk sweetly, meekly, tenderly, peaceably, and lovingly one with another. And then ye will be a praise to the Lord; and any thing that is, or hath been, or may be amiss, ye will come over in the true dominion, even in the Lamb's dominion; and that which is contrary shall be trampled upon, as life rises and rules in you. So, watch your hearts and ways; and watch one over another in that which is gentle and tender, and knows it can neither preserve itself nor help another out of the snare; but the Lord must be waited upon to do this in and for us all. So, mind Truth, the service, enjoyment, and possession of it in your hearts; and so to walk as ye may bring no disgrace upon it, but may be a good savor in the places where ye live: the meek, innocent, tender, righteous life reigning in you, governing over you, and shining through you, in the eyes of all with whom ye converse.
Your friend in the Truth, and a desirer of your welfare and prosperity therein.I.P.
Aylesbury4th of Third Month, 1667.
