“There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.” I Jn. 4:18
It isn’t so much the love from people around you that casts out fear, it is love for God that casts out fear. The more you know God the more you love Him. The more you love Him the more your love for Him is perfected. It is in that love that a saint trusts the Lord with every aspect of their life, thus casting away ANY and ALL fear.
