To cause offense with another is a very serious matter. Yet, from time to time we all do cause offense. Offenses can be caused intentionally or unintentionally. We must be careful to make every effort not to offend. And, of course, we should, also, make every effort not to take offense except for serious cause.
But what should we do when offenses come? Offenses need to be resolved quickly, or Satan will use the offense for harm! Christ illustrates to us in Like 17 how offenses should be dealt with.
