Deuteronomy 22:8 reads, "When you build a new house, you shall make a parapet for your roof, so that you will not bring bloodguilt on your house if anyone falls from it." The Passage tells us to consider others in active deeds, and this is the heart God's children should have. We should try to understand others rather than to be understood. Then, we will be a lot happier. Even if the fault seems obvious we should try to understand them thinking they may have had some reasons for making such mistakes. Then, you can have peace and rest.
