It is common for a sinner to try to cover his wrongdoing by saying someone else made me act as I did. But regardless of how one person mistreats another, he cannot cause sinful anger, ulcers, worry in the one who is mistreated. Jesus didn't get an ulcer on the cross. Instead, He handled wrongdoing righteously. That is to say, when He prayed for those who were killing Him, He assumed His responsibility in the relationship. And, in every relationship, that is exactly what He calls on us to do.
