Zwingli writes, quite famously-
I believe, then, that the souls of the faithful fly to heaven as soon as they leave the body, come into the presence of God, and rejoice forever. Here, most pious King, if you govern the state entrusted to you by God as David, Hezekiah, and Josiah did, you may hope to see first God Himself in His very substance, in His nature and with all His endowments and powers, and to enjoy all these, not sparingly but in full measure, not with the cloying effect that generally accompanies satiety, but with that agreeable completeness which involves no surfeiting, just as the rivers, that flow unceasingly into the sea and flow back through the depths of the earth, bring no loathing to mankind, but rather gain and joy, ever watering, gladdening and fostering new germs of life.
The good which we shall enjoy is infinite and the infinite cannot be exhausted; therefore no one can become surfeited with it, for it is ever new and yet the same. Then you may hope to see the whole company and assemblage of all the saints, the wise, the faithful, brave, and good who have lived since the world began. Here you will see the two Adams, the redeemed and the redeemer, Abel, Enoch, Noah, Abraham, Isaac, Jacob, Judah, Moses, Joshua, Gideon, Samuel, Phineas, Elijah, Elisha, Isaiah, and the Virgin Mother of God of whom he prophesied, David, Hezekiah, Josiah, the Baptist, Peter, Paul; here too, Hercules, Theseus, Socrates, Aristides, Antigonus, Numa, Camillus, the Catos and Scipios; here Louis* the Pious, and your predecessors, the Louis, Philips, Pepins, and all your ancestors who have gone hence in faith.
In short there has not been a good man and will not be a holy heart or faithful soul from the beginning of the world to the end thereof that you will not see in heaven with God. And what can be imagined more glad, what more delightful, what, finally, more honorable than such a sight? To what can all our souls more justly bend all their strength than to the attainment of such a life? And may meantime the dreaming Catabaptists deservedly sleep in the regions below a sleep from which they will never wake. Their error comes from the fact that they do not know that with the Hebrews the word for sleeping is used for the word for dying, as is more frequently the case with Paul than there is any need of demonstrating at present.
