Luke 5:32-36

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?

But the days will come when the bridegroom will be taken from them; and then they will fast in those days.

He told them a proverb also: No one puts a patch from a new garment on an old garment; if he does, he will both tear the new one, and the patch from the new [one] will not match the old [garment].
