Are We Tempting God?

He who holds fast to the Word alone, trusts and abides in it, does not doubt that what the Word says will come to pass; he who does not dictate aim or time or means and ways, but resigns all freely to God's will and pleasure as to when, how, where, and by whom he will fulfil his Word; he, I say, has a true living faith which does not nor can not tempt God.
