God wants to be the most important thing in your life. Sadly, many Christians let the opinions of other people control their own decisions, altering what they consider to be important.
Proverbs 29:25 says, Fear of man will prove to be a snare, but whoever trusts in the Lord is kept safe.
Your relationships with the people you're around could be a snare to you if let them control you. However, if Christ is more important to you than any relationship, then he will control your relationships, guiding you into right, godly ones. Make Christ first place in your heart, and he will control and direct your relationships.
