Q: How so?
A: Because it was sin that separated us from Him, and made us enemies; and "the blood of Jesus Christ His Son cleanses us from all sin" (l John 1:7).
---In that Christ shed His blood for us,
---He gave His life for us.
---But inasmuch as the blood is applied to us, to cleanse us from all sin,
---He gives His life to us.
In the death of Christ therefore we are crucified with Him.
From first to last this has been the work of God."
