Luke 5:30-34

Now the Pharisees and their scribes were grumbling against Jesus' disciples, saying, Why are you eating and drinking with tax collectors and [preeminently] sinful people?

And Jesus replied to them, It is not those who are healthy who need a physician, but those who are sick.

I have not come to arouse and invite and call the righteous, but the erring ones (those not free from sin) to repentance [to change their minds for the better and heartily to amend their ways, with abhorrence of their past sins].

Then they said to Him, The disciples of John practice fasting often and offer up prayers of [special] petition, and so do [the disciples] of the Pharisees also, but Yours eat and drink.

And Jesus said to them, Can you make the wedding guests fast as long as the bridegroom is with them?
