Luther and Packer on Repentance

"When our Lord and Master, Jesus Christ, said "Repent", He called for the entire life of believers to be one of repentance" (Martin Luther, thesis #1 of 95)

"Repentance means turning from as much as you know of your sin to give as much as you know of yourself to as much as you know of your God, and as our knowledge grows at these three points so our practice of repentance has to be enlarged" (Keep in Step with the Spirit [Revell: 1984], 104)
