There will always be people who speak negatively out of ignorance. Don’t take it personal. Cancel every negative utterances with the word of God. The word of God is alive and powerful.
Meditate on this scripture
For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart. Hebrews 4:12
