The man who began his letter by identifying himself as a slave …
‘Paul, a slave of Jesus Christ’ …
and who has at times in his epistle called his readers to be …
‘slaves of justice’ …
comes to the heart of his correspondence by writing …
‘For you did not receive a spirit of slavery to fall back into fear,
but you have received a spirit of adoption …’
Slaves of Christ, even slaves of justice, but for those very reasons, not captivated by a spirit of slavery.
Obviously the apostle is playing with this (and many other) metaphors in this letter.
