PREACHING AND PRACTICING
There were two doctors with the same name who lived a few doors apart. One doctor was a Christian and a lay preacher; the other doctor made no profession of faith.
One night a rather sick person, who was also a Christian,
and wanting help from a fellow believer, knocked mistakenly at the door of the non-Christian doctor.
When the door opened the patient asked, "Are you the doctor who preaches?"
"No", the medic replied, "I am the doctor who practices."
"Oh", said the sick person, "I've always understood the two things were inseparable."
Good doctrine should lead to good practice;
John wants to ask his readers; "Do your actions match your profession?"
