Witnessing should be preceded by heart; to witness you should have so strong an emotion that you become a heartistic magnet who can draw the minds of all people.
Witnessing is like creating a second self. It would be no problem if you dedicate as much heart as a mother does to nourish and care for her newborn baby.
Have you ever heard the groaning and wailing of many people trapped in the tomb of Satan? And have you ever felt righteous indignation to liberate them?
There are many who want to save good people, but few who want to raise bad and pitiful people so that they may become good and happy people. Since sinful history has lasted for 6,000 years, you must spend at least six months dedicating your heart in raising each person you have found.
