Paul the Apostle, life, Christ, truths worth fighting for

And Paul went in, as was his custom, and for three weeks he argued with them from the scriptures, explaining and proving that it was necessary for the Christ to suffer and to rise from the dead. So he argued in the synagogue with the Jews and the devout persons, and in the marketplace every day with those who chanced to be there and he entered the synagogue and for three months spoke boldly, arguing and pleading about the kingdom of God and he expounded the matter to them from morning till evening, testifying to the kingdom of God and trying to convince them about Jesus both from the law of Moses and from the prophets. And some were convinced from what he said, while others disbelieved. Acts 17:2-3,17, 19:8, 28:23-4
