Hebrews 12:3

Just consider and meditate on Him who endured from sinners such bitter hostility against Himself (consider it all in comparison with your trials), so that you will not grow weary and lose heart.  

Jesus faced bitter and hateful adversaries here on earth. We Christians should not be surprised by receiving the same in our lives. We should prepare our minds and hearts on how we will react, knowing that Jesus suffered the same thing. We do this not to lose heart or be shocked, turn away from Jesus, and be offended when opposition comes.
