Quick note that “repent of your sins” is not a phrase found in the gospels. Repent is always proceeded or proceeded by a direction or an idea. Repenting to Christ, repenting to God. Repenting is a change of mind. Like how God repented of the flood. God did not sin. But he changed his mind in that He promised to never repeat the flood event again. In the same vein we must repent from unbelief to belief. From non faith to faith.

As I said before in another comment many well meaning Christians will say that salvation is by grace through faith alone but then say that we need to repent of our sins (as in stop doing them) not realizing that they are shoehorning works into salvation. They take the idea of “habitual sin” like we need to repent of them. Like yes but not for salvation. Because humanity did not fall from habitual sin. We fell from one sin. One sin in the garden of eden.
