[Campion]

The blood of Jesus cleanses us.

That says what cleanses, not how.

[PetroniusMaximus]

"That says what cleanses, not how."


Here is the "how"

For there is no distinction: for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received by faith.

- Rom 3

God has put Christ forwards as a blood-soaked propitiation (a sacrifice that satisfies God's justice and reconciles God to man). This forgiveness God offers us is a free gift received by faith.

Just like all the sick and lame in the NT, they came, they asked by faith and they were freely healed.
