There are times when it is necessary to confront a person who sinned against you. In such cases, unconditional forgiveness is not an option. These generally involve more serious sins, not petty or picayune complaints, but soul-threatening sins or transgressions that endanger the fellowship of saints. In such situations Luke 17:3 applies: “If your brother sins, rebuke him; and if he repents, forgive him.” In such cases, if a brother or sister in Christ refuses to repent, the discipline process outlined in Matthew 18 applies.
