It does not matter who is against you at any time; if you have God on your side, then nothing and no one else really matters. People come against other person for many reasons, as well as for no reasons, at all. Whatever the reason; God knows and He can handle it. Do not worry about the problem that another person may have with you. Give the person and their problem to God, and allow Him to deal with it.
Romans 8:31 says “What can we say about all of this? If God is for us, who can be against us?”
Be blessed, be encouraged, and have a great day.
