Should Sunday preaching be necessary?

There is a true story about a woman known as ‘Auntie Esther.’

She was an elderly medical doctor in Beijing, China. She was a Christian. During the Cultural Revolution years ago, she was called in by her superior at the hospital. At the time, she was in charge of eight hospital wards. The communists were cracking down on people who followed a different faith. She warned Esther to deny her faith and join the communist party or else she would face serious persecution. 

The consequences would be a job demotion and salary reduction. Esther refused. 

A few days later, she was woken up by four nurses who roughly pulled her from her bed and marched her over to the hospital. En route, they stopped off at the barber shop and shaved off her hair. At the hospital, she was confronted to deny her faith in Jesus and join the communist party. In front of her staff, she said, ‘I can’t deny Jesus. I love Jesus.’ At that point, they threw her to the ground, tore the stethoscope from her neck and shouted at her, ‘You are no longer Esther, you are now The Fool.’ 

For the next eleven years, she was made to live in the basement of the hospital. Her new job was that of cleaning the hospital floors and toilets. Her salary of 50 Yuan was reduced to 15 Yuan. With her salary she had to feed herself and buy the cleaning materials. Towards the end of life, she said, ‘When you have Jesus in your heart, it doesn’t matter what job you do or position you have. It only matters that you love him and are faithful and loyal to him.’ 

You never have to motivate anyone who's devoted.

No one has to motivate me to love my wife. 

How much of Sunday preaching is motivation to a people who lack devotion....I'm just asking??
