Sons and Daughters, not Slaves

From another blog, a post quoting John Stott's commentary on Galatians:

Here's the quote:
“The Christian life is the life of sons and daughters; it is not the life of slaves. It is freedom, not bondage. Of course, we are slaves of God, of Christ, and of one another. We belong to God, to Christ, to one another, and we love to serve those to whom we belong. But this kind of service is freedom.
“What the Christian life is not, is a bondage to the law, as if our salvation hung in the balance and depended on our meticulous and slavish obedience to the letter of the law.
“As it is, our salvation rests upon the finished work of Christ, on His sin-bearing, curse-bearing death, embraced by faith.”
