Optimism is a wish without warrant; Christian hope is a certainty, guaranteed by God himself. Optimism reflects ignorance as to whether good things will ever actually come. Christian hope expresses knowledge that every day of his life, and every moment beyond it, the believer can say with truth, on the basis of God's own commitment, that the best is yet to come.
J. I. PackerThe whole story of the Father's Christ-exalting plan of redeeming love, from eternity to eternity, must be told, or the radical reorientation of life for which the gospel calls will not be understood, and the required total shift from man-centeredness to God-centeredness, and more specifically from self-centeredness to Christ-centeredness, will not take place.
J. I. PackerOnce you become aware that the main business that you are here for is to know God, most of life's problems fall into place of their own accord.
J. I. PackerWait on the Lord" is a constant refrain in the Psalms, and it is a necessary word, for God often keeps us waiting. He is not in such a hurry as we are, and it is not his way to give more light on the future than we need for action in the present, or to guide us more than one step at a time. When in doubt, do nothing, but continue to wait on God. When action is needed, light will come.
J. I. Packer
