Jesus is the greatest example of how to deal with other's attitudes toward us. He was morally perfect, yet many people hated him. The prophet Isaiah spoke of Jesus when he said " He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not." The life of Christ proves that some people would reject you even if you were morally perfect. The Bible teaches that we cannot have everyone's approval, and that we should not seek it because it puts us at odds with God's desire that we glorify Him and that we mature as His children. Galatians 1:10 states ".. do I seek to please men? for if I yet pleased men, I should not be the servant of Christ." In I Thessalonians 2:4 Paul says "But as we were allowed of God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, which trieth our hearts." God's approval is to be the center of our focus, not the approval of man. James 4:4 declares " know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God." I would be more concerned with someone who seemed to have everyone's approval than someone who didn't. Remember that the final judgement will be according to what the Bible (God's Word) says, not by popular opinion.
