But neither of those reasons holds any water. In John 16:8 – 11, Christ tells me that it is not my responsibility to convince people, that is the Holy Spirit’s job. Mine is simply to beg them to be reconciled to God, 2 Corinthians 5:20. Further if they do not respond, it is not because I have not been clear. The Spirit can take my fumbling and turn it into clarity in the ears of the one with whom I am sharing. If you need some proof, today is Pentecost, check out what the Spirit did in Jerusalem in Acts 2. If they do not respond Paul tells me that it is because there are other forces at work, 2 Corinthians 4:3 – 4. I have no control over whether anyone I share with comes to Christ. It does not depend on what I say. It does not depend on how well I say it. It depends on God.
The only control I have is to speak.
