There is always the question asked whether it is appropriate to forgive a person if they just keep going back doing the sinful things against you making their repentance almost as usury. I think of the troubles I've seen with addicts and compulsive liars/thieves. Jesus says yes. That doesn't mean that you have to hand them the knife with which they'll stab you in the back. By all means protect yourself and your possessions. Limit their opportunity. The forgiveness is as much for your sake as it is for theirs. A great many are suddenly controlled by both their lack of unforgiveness and feelings of violation.
