When people don’t respond to the Good News we share, we’re often disappointed. Our disappointment drives us to pursue them further. We spend more time with them trying to convince them of something they don’t want.
Jesus’ advice for us in such situations was to shake the dust off our feet. He said “If anyone will not receive you or listen to your words, shake off the dust from your feet when you leave that house or town” (Matt 10:14).
In other words, move on. There are so many who are waiting for the Good News, but we waste or efforts on those who are not interested. Of course we continue to genuinely love them. But we must move on to others with the Good News.
