I have always assumed that the date of Parousia (the Second Coming of Jesus) is fixed and that humans cannot change it. The wish that it would be soon is one of longing and fulfilment, not one of trying to influence God. Recently I heard the president of a country asking Christian leaders to ask Jesus to change his mind and come soon to remove the sinners as the police are having problems coping. (Who this is, is irrelevant to the question - he plans to rule till the Second Coming in any case so he might have ulterior motives for asking.) I then wondered if he belonged to a grouping or church (he has many wives so I am not sure about this) that believes that Christians can influence the date as some of Judaism does.
In another question on this site, the question was more about what God was waiting for before the Second Coming took place. Another question asked about the affect of prayer on God's plan. To these there are a couple of answers but this is not relevant to my question either as I want to know if there are religious groups that actively strive to bring the date forward and who they might be. Which Christian leaders feel that they can heed his call in a meaningful way and what would they do?
An example would be groups that concentrate intensely on missionary work to speed up the coming of Jesus through the promise that if the whole world have heard the message, 'then the end will come'. (Matthew 24: 14). Or a group that pray for an earlier date. Or do good works. Etc etc.
