John’s disciples and the Pharisees were fasting. Some people came to Jesus and said to him, “Why do John’s disciples and the Pharisees’ disciples fast, but your disciples don’t?”
“When you fast, stop looking sad like hypocrites. They put on sad faces to make it obvious that they’re fasting. I can guarantee this truth: That will be their only reward.
Then your fasting won’t be obvious. Instead, it will be obvious to your Father who is with you in private. Your Father sees what you do in private. He will reward you.
They don’t understand ⌞how to receive⌟ God’s approval. So they try to set up their own way to get it, and they have not accepted God’s way for receiving his approval.
