When we think of how Jesus dealt with conflict, he turned the other cheek, he forgave others, he was humble when he spoke to others, and he offered assistance even to those who didn't think much of him or the gospel he preached. Since we are not perfect like Christ, it would make sense to go to him/Holy Ghost and ask him for guidance when handling troubling issues. Be sure to have a witness when necessary when rebuking any brother or sister.
One must have a mindset prepared to deal with conflict, here are tips here: Philippians 2:1-11. Then pray, re-read text, apply the scriptures to your situation without focusing on what the person should and shouldn't do.
Permit God to convict you on your wrongs without defending or justifying your ways. Talk with trusted friends about the scriptures that you have read and your feelings. Consider this, "Plans fail for lack of counsel, but with many advisers they succeed." (Proverbs 15:22, NIV) Pray with your counselors. Afterward, act on the word (James 1:22).
