I would like to comment only on the last part of the question; witnessing today. I believe the main problem we have is that of 'fear'. Many Pastors I have shared with, tell me they struggle with this problem and in Austrlalia today many of the young breed of Pastors spend most of their time in their offices like CEOs and spend little time among their people.
Fear, our srtongest emotion, is based on something that in most cases is not true - it is a lie! I have witnessed here, 'down-under' for about 30 yrs and I cannot remember any instant of anger or violence against me. Most people today in the west have a spiritual yearning but they don't understand the Christian gospel. We need to approach people being aware that the fear we feel is only an emotion (maybe from the devil: the father of lies) once we have shared something about the gospel, we feel great and wonder why we were so frightened. We in the west have become 'soft'
and ought to remember that Christians all over the world are threatened with death if they testify to Christ.
