If one preaches the Word of God and the people doesn’t believe him, why do they then believe the one who preaches the Word of God in the Churches?

Matthew 12:27-28 And if I drive out demons by Beelzebub, by whom do your people drive them out? So then, they will be your judges. But if I drive out demons by the Spirit of God, then the kingdom of God has come upon you.

Matthew 11:17 " `We played the flute for you, and you did not dance; we sang a dirge, and you did not mourn.'

Matthew 15:12 Then the disciples came to him and asked, "Do you know that the Pharisees were offended when they heard this?"

Matthew 21:33-41 "Listen to another parable: There was a landowner who planted a vineyard. He put a wall around it, dug a winepress in it and built a watchtower. Then he rented the vineyard to some farmers and went away on a journey. When the harvest time approached, he sent his servants to the tenants to collect his fruit. "The tenants seized his servants; they beat one, killed another, and stoned a third. Then he sent other servants to them, more than the first time, and the tenants treated them the same way. Last of all, he sent his son to them. `They will respect my son,' he said. "But when the tenants saw the son, they said to each other, `This is the heir. Come, let's kill him and take his inheritance.' So they took him and threw him out of the vineyard and killed him. "Therefore, when the owner of the vineyard comes, what will he do to those tenants?" "He will bring those wretches to a wretched end," they replied, "and he will rent the vineyard to other tenants, who will give him his share of the crop at harvest time."

Matthew 22:1-7 Jesus spoke to them again in parables, saying: "The kingdom of heaven is like a king who prepared a wedding banquet for his son. He sent his servants to those who had been invited to the banquet to tell them to come, but they refused to come. "Then he sent some more servants and said, `Tell those who have been invited that I have prepared my dinner: My oxen and fattened cattle have been butchered, and everything is ready. Come to the wedding banquet.' "But they paid no attention and went off--one to his field, another to his business. The rest seized his servants, mistreated them and killed them. The king was enraged. He sent his army and destroyed those murderers and burned their city.
