On his return home Joseph Wood wrote him the following letter:--

Newhouse, 10 mo. 24, 1803

BELOVED FRIEND, JOHN YEARDLEY,

Thou hast often been in my remembrance since I last saw thee, accompanied
with an earnest desire that the seed sown may prosper and bring forth
fruit in its season, to the praise and glory of the Great Husbandman, who,
I believe, is calling thee to glory, honor, immortality, and eternal life.
And O mayest thou be willing in this the day of his power to leave all and
follow him who hath declared, "Every one who hath forsaken houses, or
brethren, or sisters, or father, or mother, or wife, or children, or
lands, for my name's sake, shall receive an hundred-fold, and shall
inherit everlasting life."

Not that we should be found wanting in our duty to our near connexions,
for true religion does not destroy natural affection, but brings and
preserves it in its proper place. When our earthly parents command one
thing, and the Almighty another, it is better for us to obey God than man,
and herein is our love manifested unto him by our obedience to his
commands though it may sometimes clash against our parents' minds. At the
same time it is our duty to endeavor to convince them, that we are willing
to obey all their lawful commands, where they do not interfere with our
duty to Him who hath given us life, breath, and being, and mercifully
visited us by his grace. I thought a remark of this kind appeared to be
required of me, apprehending if thou art faithful unto the Lord, thou wilt
find it to be thy duty at times to leave thy worldly concerns to attend
religious meetings, which may cause thee deep and heavy trials; but
remember for thy encouragement, the promise of the hundred-fold in this
world, and in that which is to come, eternal life.

Thou art favored with a pious though afflicted mother, and a
religiously-exercised elder brother, who, I doubt not, will rejoice to see
thee grow in the truth. May you all be blessed with the blessing of
preservation, and strengthened to keep your ranks in righteousness, and
may you be a strength and comfort to each other, and hold up a standard of
truth and righteousness in the neighborhood where your lot is cast. Do not
flinch, my beloved friend; be not ashamed to become a true follower of
Christ. When little things are required of thee, be faithful; thus shalt
thou be made ruler over more; when greater things are manifested to be thy
duty, remember the Lord is
