The stream gives nothing to the fountain. The beam gives nothing to the sun, for it issues from the sun. Our very blessing of God is a blessing of his.
It is from his grace that we can praise his grace; and we run still into a new debt, when we have hearts enlarged to bless him.
We ought to have our hearts more enlarged, that we can be enlarged to praise God. – Richard Sibbes, An Exposition of 2 Corinthians 1
