From Spurgeon Sermon 979 "Faith and Regeneration"

"Now we go a little further. True faith is reliance. Look at any Greek lexicon you like, and you will find that the word pisteuein does not merely mean to believe, but to trust, to confide in, to commit to, entrust with, and so forth; and the marrow of the meaning of faith is confidence in, reliance upon. Let me ask, then, every professor here who professes to have faith, is your faith the faith of reliance? You give credit to certain statements, do you also place trust in the one who glorious person who alone can redeem? Have you confidence as well as credence? A creed will not save you, but reliance upon the Anointed Saviour is the way of salvation. Remember, I beseech you, that if you could be taught an orthodoxy unadulterated with error, and could learn a creed written by the pen of the Eternal God himself, yet a mere notional faith, such as men exercise when they believe in the existence of men in the moon, or nebulae in space, could not save your soul. Of this we are sure, because we see around us many who have such a faith, and yet evidently are not the children of God."
