I received the following in my mail box not to long ago and I thought it was very fitting.
For thou shalt be his witness unto all men of what thou hast seen and heard.
There is a large amount of ineffective Christian testimony among us today. Much of it is well-intended, I am sure—honest and sincere. We do the best we can with what we have. But our performance turns out to be something like that of the salesman promoting fountain pens. He tries to make a case for his product, but his would-be customers know he really thinks ballpoints are far more practical.
Too much of our Christian witnessing is unconvincing because we have not been convinced. We are ineffectual because we have not yet capitulated to the Lord from glory. It is like the proselyte making proselytes….
Perhaps this is happening because we are trying to plan how everything should happen. Everyone of us reads a little how-to book on witnessing. We try to do it the way we have been taught. But it is perfunctory and without any contagious element. If angels can weep, they must weep salty tears upon seeing a proselyte who has never really met the Lord making another proselyte who will also never meet the Lord.
