Christians sometimes make themselves into elephants afraid of mice. You have the Creator of the universe on your side; not to mention, you've been given eternal life. 'Whom or what shall you fear?' To be afraid of anything other than God himself is like an insult to God.

You are the enemy and a vessel through which the cure flows - if Christ lives in you, then you are an embodiment of the very shot this hostile and crying world needs as it, in every waking moment, struggles belligerently to resist.

Excuses will become self-refuting. No man who does not believe that Jesus is the perfect, sinless Son of God can, in his desperation and love for sin, reasonably use and misconstrue Jesus' words that unless a Christian is perfect, then that Christian cannot judge sin. Otherwise this non-believer is unconsciously entertaining a belief that Jesus, unlike any other man to ever live, was indeed perfect and sinless in His judgments and therefore that Christian is supposed to be like Him.
