Whenever 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.'
