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. PackerHave you been holding back from a risky, costly course to which you know in your heart God has called you? Hold back no longer. Your God is faithful to you, and adequate for you. You will never need more than He can supply, and what He supplies, both materially and spiritually, will always be enough for the present.
J. I. PackerThe simple statement, 'God is for us', is in truth one of the richest and weightiest utterances that the Bible contains.
J. I. PackerGod was happy without humans before they were made; he would have continued happy had he simply destroyed them after they had sinned; but as it is he has set his love upon particular sinners, and this means that, by his own free voluntary choice, he will not know perfect and unmixed happiness again till he has brought every one of them to heaven. He has in effect resolved that henceforth for all eternity his happiness shall be conditional upon ours.
J. I. Packer
