John the Baptizer warned people to bear fruits worthy of repentance, and people wanted to know what that meant,
“So the people asked him, saying, ‘What shall we do then?’ He answered and said to them, ‘He who has two tunics, let him give to him who has none; and he who has food, let him do likewise.’ Then tax collectors also came to be baptized, and said to him, ‘Teacher, what shall we do?’ And he said to them, ‘Collect no more than what is appointed for you.’ Likewise the soldiers asked him, saying, ‘And what shall we do?’ So he said to them, ‘Do not intimidate anyone or accuse falsely, and be content with your wages’” (Luke 3:10-14).
Share, do not defraud, do not bully, do not bear false witness, and be content, were the things that John told them.
Stop doing what is wrong, and start doing what is right. So then, what do you need to do to repent?
