Oh, how rare are the Christians who speak with a tender heart and have a theological backbone of steel.
John PiperWhenever your heart starts to be anxious about the future, preach to your heart and say, 'Heart, who do you think you are to be afraid of the future and nullify the promise of God? No, heart, I will not exalt myself with anxiety. I will humble myself in peace and joy as I trust this precious and great promise of God - He cares for me.'
John PiperPeople are not prepared or able to rejoice in suffering unless they experience a massive biblical revolution of how they think and feel about the meaning of life. Human nature and American culture make it impossible to rejoice in suffering. This is a miracle in the human soul wrought by God through His Word.
John PiperSin is what you do when your heart is not satisfied with God. No one sins out of duty. We sin because it holds out some promise of happiness.
John Piper
