The biggest barriers

to effective evangelism according to the prayer of Jesus are not so much outdated methods, or inadequate presentations of the gospel, as realities like gossip, insensitivity, negative criticism, jealousy, backbiting, an unforgiving spirit, a 'root of bitterness', failure to appreciate others, self-preoccupation, greed, selfishness and every other form of lovelessness. These are the squalid enemies of effective evangelism which render the gospel fruitless and send countless thousands into eternity without a Saviour. 'The glorious gospel of the blessed God', which is committed to our trust, is being openly contradicted and veiled by the sinful relationships within the community which is commissioned to communicate it. We need look no further to understand why the church's impact on the community is frequently so minimal in spite of the greatness of our message. We are fighting with only one hand!
