True Christians consider themselves not as satisfying some rigorous creditor, but as discharging a debt of gratitude.

Colossians 2:13-14:  “And when you were dead in trespasses and the uncircumcision of your flesh, God made you alive together with Him, when He forgave us all our trespasses, erasing the record that stood against us with its legal demands.  He set this aside, nailing it to the cross.”

William Wilberforce (1759-1833) was a member of the British Parliament.  He became a major figure in the movement to abolish the slave trade and slavery itself in the British Empire.
