It’s not only that, but you must also turn from your sin and towards God. That is, make a conscious commitment not to sin.

“Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord,” Acts 3:19

(2) "Jesus answered, “Do you think that these Galileans were worse sinners than all the other Galileans because they suffered this way? (3) I tell you, no! But unless you repent, you too will all perish.” Luke 13:2-3
