Has Piper ever read Erskine?

I’m really interested to know if John Piper has ever read Ebenezer Erskine. Compare the following extract from Ebenezer Erskine’s sermon on the first commandment, “Thou shalt have no other gods before me”, with an article from John Piper’s church website:

This commandment requires us to believe and be persuaded, that this glorious God is the chief good of the rational soul; that as his glory is to be our ultimate end, so our chief happiness lies in the enjoyment of him alone; Thou shalt have no other gods before me”; i.e. Thou shalt place thy chief happiness in the enjoyment of me, who “am the Lord thy God.” So that, when God commands us to have him as our God, he commands us to be happy for ever in himself, and to say with David, “Whom have I in heaven but thee? and there is none in all the earth that I desire besides thee.”

This extract is from the Bethlehem Baptist church’s article “Quest for Joy”

God made us to magnify his greatness – the way telescopes magnify stars. He created us to put his goodness and truth and beauty and wisdom and justice on display. The greatest display of God’s glory comes from deep delight in all that he is. This means that God gets the praise and we get the pleasure. God created us so that he is most glorified in us when we are most satisfied in him.
