But when they opposed Paul and became abusive, he shook out his clothes in protest and said to them, “Your blood be on your own heads! I am innocent of it. From now on I will go to the Gentiles.” – Acts 18:6 NIV
This passage is reminiscent of Ezekiel as a watchman (Ezek. 3:16-21), where God calls Ezekiel to warn the people of God’s judgement on their sin. If he warns them, then they are responsible for their response. If he does not warn them, then he bears responsibility for their blood. In this passage Paul has been testifying to the Jews that Jesus was the Messiah, filling the role of Ezekiel’s watchman. But many of them opposed his message and his response to them mirrors what Ezekiel might have said: I warned you and am innocent of the judgement that will fall on you; you bear responsibility for your blood.
I am not Ezekiel, nor am I Paul. But I wonder how much responsibility I have for those I could have shared Christ with, warning them about their impending judgement, and yet failed to do so?
