Christian living is more than talking to others about Jesus and salvation. It is living by the power of God. "For the Kingdom of God does not consist in words, but in power." Paul talks further about this power in 1 Corinthians 4: 19, 20. "I will come to you soon if the Lord will let me, and I shall find out whether these proud men are just big talkers or whether they really have God's power."
There are many big talkers today. In the movie, O God, an important evangelist received this message from God: "You stopped saying My words a long time ago." I think that this indictment applies to much of the talking in the name of God in Christian circles today whether it is on tape, in books, sermons, magazines, radio programs, or person to person. There are many words, but little power.
But what is this power? I don't know how to define it but I have felt it in certain Christians. It is a mysterious aura of truth that created in me a desire to find that special something that they had. They made me hungry and thirsty for God. When they spoke I heard God speaking to me. Watchman Nee supports this idea. "The Lord does not set us here first of all to preach or to do any work for Him. The first thing for which He sets us here is to create hunger in others. No true work will ever begin without a sense of need being created and that hunger can be created only through those who carry the impressions of God."
Talk is easy and anyone can talk. But only the words of a few create in others a hunger for God. If we really want to be true witnesses we will ask God to "impress" us with Himself. Then we will be His witnesses. What more is there to say!
