I really loved the clear imagery of this quote from a book I started to read over the weekend:
God’s word is like a magnet: it draws and attracts God’s children, while repelling those who are not His. It is in this sense that God’s word supplies a crucial, polarizing test among those who claim to be the followers of God (Michael Beasley, The Fallible Prophets of New Calvinism, loc. 481).
