There will be people who encourage you to deal harshly with the prodigal, summarily rejecting him or her because they are ”sinful and rebellious,” and your duty as a Christian demands that you show tough love.
Tough love is tough not because it’s grim and rigid, but because it’s painfully difficult. (It’s also a pop psychology phrase that you don’t find in the Bible.)
Luke 17: 3 tells us, “If your brother sins, rebuke him, and if he repents, forgive him. If he sins against you seven times in a day, and seven times, comes back to you and says, ‘I repent,’ forgive him.”
By all means, lock your house, put away money and charge cards, protect yourself from your prodigal when they are in an untrustworthy state, but always remember — this is your child. Ultimately, you don’t want to sever them from the possibility of ever having a relationship with you, when they come back to their senses.
