Matthew 9:13-15

But go and learn what this means: ‘I desire mercy and not sacrifice.’ For I did not come to call the righteous, but sinners, to repentance.” Then the disciples of John came to Him, saying, “Why do we and the Pharisees fast often, but Your disciples do not fast?” And Jesus said to them, “Can the friends of the bridegroom mourn as long as the bridegroom is with them? But the days will come when the bridegroom will be taken away from them, and then they will fast.
