Review of David Silversides’s The Free Offer: Biblical and Reformed, from “Book Reviews,” in Banner of Truth, 507 (December 2005), p. 22.
Tony Byrne’s comments at the end are very important:
“Moreover, [Iain] Murray thinks God’s universal love necessarily entails that God desires the highest good (i.e. the eternal salvation) of all men in the revealed will… this also answers the Gillite [from John Gill] position that God loves all merely in a temporal sense, but doesn’t desire their highest good, or in the sense of their eternal salvation.”
