Matthew 9:15
15 Jesus answered them: ‘When a man marries, his friends cannot be sad. They cannot refuse to eat food while he is with them. But there will be a time when people will take the man away from his friends. At that time his friends will choose to fast.’
9:15In this picture story, Jesus is like the bridegroom. Those who follow him are like his friends at the marriage. Jesus will not always be with them. That will be the time when they will stop eating for some time to pray.
