Hebrews 9:26-28
26 for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself. 27 And just as it is appointed for man to die once, and after that comes judgment, 28 so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him.

It has been some 2000 years since our Lord ascended into heaven to take His rightful place at the right hand of God the Father. The wait has certainly been long, has it not?
