There is no room for copy cats in the Kingdom of God. God has created each person in their own unique way with each person having the gift and talent that He desires them to have. Each person needs to work with what God has entrusted them with. Being jealous, envious, wanting to compete, trying to intimidate others because of their gift, copying or stealing others ideas and passing them off as your own is not of God. Instead of a person operating in all of those illegal spirits; they should take it up with God and not come against the person who God has entrusted with the gift or talent. He is the one who gave it to them. They did not give it to themself. There is a reason and a wisdom in everything that God does, even in assigning gifts and talents to people.
Be blessed, be encouraged, and have a great day.
