Don't believe Satan's lie. It's not what's on the inside that counts. At the end of the Day what really matters is what's on the outside.
Take some of the blood and put it on the sides and tops of the door-frames... when I see the blood, I will pass over you. (Ex 12:7,12)
Christ our Passover Lamb has been sacrificed (1 Corinthians 5:7)
Your salvation lies entirely outside yourself.
