Oh, we’re not talking about the same thing. I mean Jesus’ act of dying for us, and you mean our act of killing him. Why certainly our killing him was unjust! But he freely died in obedience, and his act was never unjust. It couldn’t be. Two wrongs don’t make a right, and the spotless lamb wouldn’t have been spotless and couldn’t have saved us had he been unjust in any way. Our unjust act didn’t save us – for how could injustice save and how could we ever save ourselves? – but his merciful act saved us.
