We are all suffering in some way. We are all human, all subject to sin, so there is no way around the fact that we all suffer. In Matthew 14:14, Jesus looked out over the crowd and healed them because he had compassion on them.
Instead of scoffing at someone who is rude in the grocery line or show a cold shoulder to a friend who is short with us, let us show compassion on them, just as Jesus did. Everyone is hurting in some way, I challenge you (and myself) to have compassion on all you meet.
You show the greatest love and the most compassion, let that flow through me so that I may show love and compassion to all I meet, that they may see a glimpse of you through me!
