What bears fruit?

I am often amazed to hear Christian evangelists being accused of causing nothing but trouble by public preaching.  They will be asked, "do you see this producing any positive fruit?"

For years I have watched farmers preparing raw land for future crops.  Often it starts with heavy equipment ripping out brush or trees to be burned.

Then, rippers go through the field literally tearing up the soil revealing large rocks.  Next a large piece of equipment sorts out the rocks and transfers them to a truck to be hauled away.  Often a crew of laborers literally walk through the field picking up rocks that the equipment have missed.  This usually takes up most of the first year.  Then comes plumbing in irrigation lines.  Before the field is ready for planting city folks drive by these fields and scratch their heads with no clue what kind of fruit will be the final outcome.  Next, at great expense, seed or small trees are planted and fertilizer is applied.  In the case of fruit trees or vineyards there will be several years of further expense before anyone can expect to see actual "fruit".

The evangelist is expected to produce "fruit" as he is tearing up the soil that has been overgrown with weeds and cults.  Then when he is scattering the seed of the gospel he will hear church folks say, "we don't do it that way" when in fact they have never done any form of outreach.  I sometimes hear church folks say that they would like to go on the mission field when in fact they can't even reach out to their neighbor.  So why do they think they will instantly become an evangelist if they fly to a foreign country when they have never tried out their skills of evangelism in their home town?
