What price our ransom?
We can never ransom ourselves,
or deliver to God the price of our life;
For the ransom of our life is so great,
that we should never have enough to pay it,
In order to live for ever and ever,
and never see the grave.
(Psalm 49:6-8, BCP)
Even the nations are like a drop from a bucket,
and are accounted as dust on the scales;
see, he takes up the isles like fine dust.
Lebanon would not provide fuel enough,
nor are its animals enough for a burnt offering.
All the nations are as nothing before him;
they are accounted by him as less than nothing and emptiness.
(Isaiah 40:15-17, NRSV)
Ergo, the Cross.
