How compassionate is it really to pay your taxes and never lift a finger to help someone in need. Just shrug your shoulders, it's the government's job. You've got the same number of people in poverty now that you had before welfare, but you have more people skilled at manipulating numbers.
Bottom line: My church and civic organizations are faster and more efficient than government programs.
Using scripture to back tax plans is wonky. Jesus said to get out there and help people. That means donate money to a soup kitchen and better yet, go and serve at one.
Donating someone else's money to the people you consider in need isn't going to get anyone to heaven, so if paying your taxes clears your conscious, then keep voting. Just remember that the devil knows more scripture than the average self proclaiming Christian.
