Our prayers are for personal issues, not global vengeance.
You have to keep those two separate in your mind, or you can become like Harold Camping!
#1...Surely, you've heard the phrase "imprecatory psalms"??? [If not, please proceed to about 14 or so to become familiarized...5, 10, 17, 35, 58, 59, 69, 70, 79, 83, 109, 129, 137, 140]. Indeed, this is less than 10% of the Psalms...as indeed over 90% of our prayers should focus on things beyond righteous indignation...but there is such a thing in the Bible as that...righteous indignation.
Look it up sometime. Familiarize yourself (enough) with these Biblical concepts as relayed by a socially righteous, holy and just God.
As a matter of fact, the Jews have a tradition called "Purim" related to this concept of righteous indignation...based upon what occurred in the book of Esther.
So...by all means...censor this Jewish tradition if you will -- if it falls outside the realm of what you recognize as your given theological "purity..."...And while you're at it, take some scissors & cut out all those imprecatory Psalms. [You can lecture these Psalmists for including them in the Psalms when you get to heaven, scolding them for "encouraging" global vengeance, right?]
And #2, if things like Jewish holocausts or mass murder (like abortion & other violent acts) doesn't "distress" you, please go ahead & object to other portions of scripture...like Ezekiel 9...where Ezekiel has this vision that those NOT distressed over the violence going on in a city would be the ones targeted for destruction by God's angels of death.
Why...go ahead & preach your blase' "gospel" of "tolerance" of all things evil...Something that some people in some cultures have not had that "luxury" thru all generations.
