“And none of this threatens sola fide in the slightest because to maintain that faith is the sole instrument in justification does not deny that God uses other secondary instruments, always subsidiary to the primary instrument, which is faith alone. Those other subordinate instruments would include, but not be limited to, preaching, Gideon Bibles, tracts in the laundromat, billboards, sermon tapes, baptism, godly mothers, and so on.”
