There are certainly misuses and abuses of both the biblical interpretation and application regarding the answer to this question for us after the New Testament days, but that is not to hinder or excuse any Christian from researching and living by the question's answer. More so, it's never a 'should' but a 'want' (desire) to give. Giving is a desire when we become a Christian, in which we have trusted in Christ to follow him. There certainly seems to be extremes in life, especially regarding topics like 'church giving' or 'tithing', where one answers the question with pragmatic or spiritualized reasons to give or not give. Instead of extremes or bi-polar opposites, let's find sound answers and live differently than the world for the sake of God and his good news to the world.
