Everyone feels afraid many times during life. However, when the Bible instructs us to “fear not,” it doesn’t mean not to feel afraid; rather, it means to decide to press on even in the face of fear.
Indeed, we are encouraged in 1 Corinthians 16:13 to be men of courage; be strong. So, next time you feel afraid, overcome your feelings through prayer so that you can “be strong and courageous.”
