Jesus begins with some teaching on how we should be concerned about other people鈥檚 sin. If we love other people, we won鈥檛 want them to pursue self-destructive behaviors. But we are also supposed to forgive, so this concern is never done in a judgmental way. He then goes on to challenge people not to expect God to be impressed by our good deeds or forget to thank him for the things he does for us.
These are all difficult challenges. We have a tendency to either go to the extreme of thinking everyone is responsible for his or her own sin, so someone else鈥檚 action are not our business or to think we have the right to judge everyone else鈥檚 behavior. We are supposed to love others enough to help them not make mistakes, but judgment is not a part of that. We also tend to do the opposite of what Jesus says about thankfulness. We want God to be thrilled with each of our acts of obedience and sacrifice for him but then don鈥檛 thank him for what he does for us.
