Followers of Jesus should obey his commands to help the poor and defenseless. But I’m pretty sure He meant for me to use my money, not yours.
Giving away other people’s money is not charity, and it isn’t what the Bible asks of us. There are many kind hearted atheists, agnostics, Hindus, Muslims, Rotary Club members, etc. who do good deeds, too. The central message of the Bible isn’t the Social Gospel, it is the real Gospel: That Jesus came to save lost sinners.
If you want to give money, that is generosity. But if I vote for policies that take your money and give it away by force of law, that isn’t generosity. That is more like coveting, where I am accusing God of not distributing wealth properly in the first place. It means the government must take it from one to give to another.
Note that I am not against any government help for the poor. I just think that much of it has been counterproductive. The “War Against Poverty” was a flaming disaster and doomed countless children to grow up poor and fatherless. That isn’t love. We shouldn’t ask the government to do what the church should be doing, because the government can only dole out money in a soul-less fashion.
We are part of the richest 1% of people who have ever lived and we should be giving lots of our own money away and addressing people’s spiritual needs at the same time.
