“We put no obstacle in anyone’s way, so that no fault may be found with our ministry, but as servants of God we commend ourselves in every way.” (2 Corinthians 6.3-4a)
One of the toughest challenges in Christian apologetics is proving the truth and reliability of our message. Men may agree that what we say is in line with Scripture, but then dismiss Scripture as being false and so leave us with nothing. However, the power of a faithful Christian witness can defend us against this.
I am not talking about a witness in the popular evangelical way. In this way it is just another word we have coopted to mean yelling a cold, lifeless, ineffectual spiel at someone. No. By witness we should mean a life lived. It is not the evangelist who is witnessing; it is the lost who are witnessing him! They witness how what he does backs up what he says. They witness a breathing example of the message being fulfilled. Paul stakes the whole call upon his faithful witness, knowing that the commendation of his life will only give that much more evidence for the gospel that in 2 Corinthians 6.2 he claims is so urgent.
