what CAN WE DO to make Jesus COME BACK quickly?

I would like to see Jesus return before it's too late.
I am very old and my pastors have been promising me that Jesus will definitely be back before 1960 and then kept delaying the date every 7 years.

In the ancient times of old testament stories, God used to get quite angry with people doing the wrong things and used to come down hard on the villains with floods, wars, pestilences, locusts, droughts, turn them into pillars of salt and other general Acts of God deterrents.

I think that we have now evolved and civilized to the point where God is pleased with our behaviour so he is no longer concerned about having to return?
after all he did say : I will return within this generation?
but that generation went and no-one came?
Have we been stood up?

If we all start behaving badly and run amok maybe he will come to bring back law and order?
