It has been written and we have been told

Abomination ---a vile, shameful, or detestable action, condition, habit, etc.

Desolation -- Devastation; ruin

The end of times, no one knows, not even Jesus himself knew the day and time only God our Father knows, he has however, given us signs of many in past and present to recognize future events. One book in the bible, Daniel is one of our greatest indicators of when we should become aware the time is near and with it the phrase “abomination that causes desolation” is mentioned many times in different contexts but the meaning itself of what is spoken of will always be the same, it is up to man (I say man since he refers to both male and female hence the word human) to decipher what the “abomination that causes desolation” actually is.

Many theories of this phrase has been spoken of, and could have referred to many incidences in time since the writings, including the crucifixion of Jesus and many before and after. more
