My dear Friends, be not carried away by good words and fair speeches, but everyone have hold of the Truth in yourselves by which you may be stayed upon Christ, your bread of life, the staff of your heavenly and eternal life.

Now Friends, who have denied the world's songs and singing, sing you in the Spirit and with grace, making melody in your hearts to the Lord. You that have denied the world's formal praying, pray always in the Spirit.

You that have denied the world's giving thanks and their saying of grace and living out of it, do you in everything give thanks to the Lord through Jesus Christ.

And you that have denied the world's praising God with their lips, while their hearts are far off, do you always praise the Lord night and day.

And you that have denied the world's fastings, keep the fast of the Lord that breaks the bond of iniquity and lets the oppressed go free, that your health may grow and your Light shine as the morning. --Letters of George Fox 167
