There was another weakness that Jesus had seen in people, especially in the Pharisees. They loved to show off their good deeds. He had to speak about this too.
"When you give something to the poor," he said, "don't make a great noise about it, like some people I could mention, who want to impress everybody with how generous they are. If you give anything, keep quiet about it. God will know what you have done, and that's enough.
"It's the same with prayer," Jesus continued. "Don't stand praying on the street corners where everyone can see you. There are many people who do that. When you pray, go into your own room and pray with the door closed. God will hear you, and he is the only one who needs to hear."
Jesus had his admirers. Some people admired him so much that they began to call him "Master" and "Lord." But Jesus did not think that they were all in earnest. He spoke plainly about this also.
"It won't do you any good to come saying, 'Lord, Lord,'" he said, "unless you do the things God expects of you. Someday, I suppose you will come and tell me of all the wonderful things you have done in my name. And then I will have to say to you: 'I don't even know who you are. Go away!'
"If anyone hears my teachings, and does what I tell him to do, he will be like a man who builds his house upon a rock. The rain comes down and the wind blows, and the house keeps on standing there, because it is built upon a rock. You will be strong like that house, if you do as I say. But anyone who hears my teachings and pays no attention to them is like a man who builds his house upon the sand. When the rains and the floods and the winds come, the house will fall down and that will be the end of it. You will be weak like that house, if you do not obey my words."
