And do not [for a moment] be frightened or intimidated in anything by your opponents and adversaries, for such [constancy and fearlessness] will be a clear sign (proof and seal) to them of [their impending] destruction, but [a sure token and evidence] of your deliverance and salvation, and that from God.
Fearlessness. I love this verse--especially in the Amplified version of the Bible. Your fearlessness will be a sign to your enemy of his impending destruction!! He knows he's doomed when you stand without fear. As long as you fear, he has you right where he wants you. Defeated.
Stand fearlessly!! It's a sure sign that God will deliver you! (I honestly think this is the biggest spiritual battle we each face.)
