Many times people will oppose us just like in the post Boldness Given by the Holy Spirit when Peter proclaimed Christ as the Savior before the group that had crucified Him.

Remember, God is with us to fight our battles. Here is a video assuring that we are never alone during difficult times: I Am Not Alone – Kari Jobe.
Be strong and of good courage; do not be afraid, nor be dismayed, for the Lord your God is with you wherever you go. – Joshua 1:9
