It is amazing how much of our life is driven by emotion and how those emotions quite often negatively impact our lives. When someone treats us poorly (however we define "poorly" at the moment which usually is much broader than we want others to define our actions toward them as poor), we rarely respond with "It is unfortunate that this person is having a bad day or even worse, has a bad life and probably a worse life than me and this current response to their circumstance is manifesting in actions that are directed toward me and although it makes me feel bad, I should see this as an opportunity to pray for them and ask God to intervene in their trials and tribulations". But instead we treat them poorly back.
Lord, when I feel I am wronged, please help my response to be a blessing to the other person as it is not only the right thing to do but the more productive thing to do.
