Take initiative to restore peace
We must take the initiative to restore peace. Jesus taught that it makes no difference whether you have wronged your brother or he has wronged you. Either way, you are always responsible to initiate efforts toward peace (see Matthew 5:23-24 and 18:15). If we are serious about intently pursuing peace, we won’t be concerned about which of us is the offending party. We will have one goal: To restore peace in a godly manner. Unresolved conflict between believers is sin and must be treated as such; otherwise, it will spread throughout the body like cancer until it requires radical spiritual surgery. Far better to deal with it when it is easily contained.
