It really doesn't matter what people say about you or to you.
If you are a born again Christian then the above is a true statement. Hopefully, you have studied the Word of God to find out what God says about each of us. The world can try to tear us down, ruin our reputations, slander our names...yell at us and all those things that the world does.
How we respond is so very important to success in our Christian walks and gaining happiness with contentment in every situation. We are a holy priesthood, a royal generation. We are adopted sons and daughters of the One Living God. We are saved and bought by the blood of Jesus. We are joint heirs with Christ to the throne, and we serve the King of Kings and Lord of Lords. We are citizens of the Kingdom of God when we fly the banner of the King.
With credentials like that, the enemy will always seek to steal from us, to kill us (our reputations, our spirits, our faith), and to destroy us (financially, personal and professional lives). We must continually be on guard, resting in the shadow of the Almighty, but prepared for battle wearing our armour.
