When someone mistreats you, you should always remember that it is only the enemy who is using that person (like a puppet) to try and get to you.
You can also be used by the enemy like a puppet – if you let him. For example if you take offence or if you don’t live a life that glorifies God in every area of your life.
God also uses people, but as vessels. A vessel is a canal that is used to transport something.
God uses people to “transport” His Word and love.
You have to choose if you are going to be a vessel which God can use or a puppet which the enemy will use (and in the end) to embarrass you.
Therefore if anyone cleanses himself from the latter, he will be a vessel for honor, sanctified and useful for the Master, prepared for every good work.
2 Timothy 2:21
