Acts 20:21 testifying to Jews, and also to Greeks, repentance toward God and faith toward our Lord Jesus Christ.
When you get good news, who is the first person you will tell? I have a few people who I always try to get a message to when something really good happens; but I always thank God!
When we hear the good news, the Gospel, we should be wanting to take that news and go and tell as many people as we can.
Paul may have had a rough time with the Jews but he was still willing to teach them about Christ after he found out the good news. We should be willing to go out to tell everyone too.
