How to be brave

How can I be scared of no one

 I hope this helps. I will pray for you

2 Timothy 1:7," For the spirit God gave us does not make us timid but gives us power, love, and self-discipline.

Joshua 1:9, “Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.”

"Be strong and courageous. Do not be afraid or terrified because of them, for the Lord your God goes with you; he will never leave you nor forsake you."

“But you, take courage! Do not let your hands be weak, for your work shall be rewarded.”

The LORD is my light and my salvation-- whom shall I fear? The LORD is the stronghold of my life-- of whom shall I be afraid? When evil men advance against me to devour my flesh, when my enemies and my foes attack me, they will stumble and fall. Though an army besiege me, my heart will not fear; though war break out against me, even then will I be confident.

I don't know if you're religious but God is always with you to keep you strong and faithful even when you feel scared.
