Since I am one of those Christians who struggle very much with despair and self-loathing because of sin, this devotion by Martin Luther really struck me right in the heart. I never considered this before as part of our Mortification of Sin. I pray God will use this in your heart as well for your edification.
by Martin Luther
21 He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him. 2 Corinthians 5:21 (NASB)
