Acts 28:23-24 They arranged to meet Paul on a certain day, and came in even larger numbers to the place where he was staying. He witnessed to them from morning till evening, explaining about the kingdom of God, and from the Law of Moses and from the Prophets he tried to persuade them about Jesus. Some were convinced by what he said, but others would not believe. 

No matter how much evidence we present to others about Christ, there will always be those who refuse to believe. Father, give me boldness to speak to all people about You; in spite of the opposition I may face.
