“So when the devil throws your sins in your face and declares that you deserve death and hell, tell him this: ‘I admit that I deserve death and hell, what of it? For I know One who suffered and made satisfaction on my behalf. His name is Jesus Christ, Son of God, and where He is there I shall be also!’”- Martin Luther
We have complete confidence in our faith because we have completely confidence in the finished work of Christ Jesus–we must cling to him when we feel pressured to add on to our salvation from others.
