When we allow the Holy Spirit to empower us, we really can show kindness to others by demonstrating love to our enemies; by lending without worrying about the return; by showing mercy to those Jesus tells us in several places that when we practice kindness to others we are actually showing kindness to Him.
Like Jesus, we will be insulted, mistreated and unappreciated. When it happens, don’t get upset and stew over it. Humble yourself and deflect the insult. Jesus said, “Don’t let it get to you. Rejoice because that’s how they treated the prophets!”
