it has a whole slew of things written by Piper, a link to his audio sermons, and other books which I’m sure are very good as well.
Since he did not spare his own Son, but delivered him over for us all, he will, with absolute moral certainty, give us all things with him. Really? All things? What about "tribulation, or distress, or persecution, or famine or nakedness, or peril, or sword" (Romans 8:35)? The answer is in this magnificent quote from John Flavel from 350 years ago:
He spared not his own Son, but delivered him up for us all; how shall he not with him freely give us all things?" (Romans 8:32). How is it imaginable that God should withhold, after this, spirituals or temporals, from his people? How shall he not call them effectually, justify them freely, sanctify them thoroughly, and glorify them eternally? How shall he not clothe them, feed them, protect and deliver them? Surely if he would not spare this own Son one stroke, one tear, one groan, one sigh, one circumstance of misery, it can never be imagined that ever he should, after this, deny or withhold from his people, for whose sakes all this was suffered, any mercies, any comforts, any privilege, spiritual or temporal, which is good for them.
God always does what is good for us. If you believe that he gave his own Son for you, this is what you believe. And all of the Christian life is simply the fruit of that faith. Look to Christ. Look to the love God. Live in love. And fear no more.
