From the ever provocative and incisive Hoekendijk:
In Jesus, people are introduced into an unprecedented history of free men, a continuous risky adventure with always hazardous improvisations; of each of the years that we count from Jesus Christ, we only know that it will be a “year of our Lord” and that must suffice. Now then, “When anyone is united with Christ, there is a new world; the old order has gone, the new order has already begun.” (II Cor 5:17). I think that here lies the heart of the eschatological existence. A new act of creation has taken us out of the oppression of our closed and too little world and put us in the open history with wide horizons, in the middle of ultimate realities, which Jesus directs toward us from the ultimate. Only the man who is open toward this future is up to date; only he who expects that this new reality not only has evident surplus value over the old today, but also that it will again get superiority over it, only he deserves to be called sanguine.”
