As free - from sin, and to duty: 'the Lord's freemen' (1 Corinthians 7:22), connected with 1 Peter 2:15, doing well as being free. "Well doing" (1 Peter 2:15) is the natural fruit of being Christ's freemen, made free by "the truth" from sin's bondage. Duty is enforced to guard against licentiousness; but the way is by love and the holy instincts of Christian liberty. We have given principles, not details.
