Nowhere is scripture does it say that we should demand that the government distribute wealth by taking it from one person and giving it to another. That is NOT biblical. What IS biblical is that we as the church should give out of our own pockets according to our own conscience to people in need.
Nowhere in scripture does it say that we should demand that the government prohibit abortions. Nowhere in scripture does it say that we should demand that the government make killing or stealing illegal. Nowhere in scripture does it say we should demand the government make ANY kind of law or program whatsoever. But you want to use that argument to argue against one thing that doesn't fit your politics. Well, it doesn't work that way.
In the same way a Christian who is pro-life will do whatever he can to "demand that the government" make abortion illegal, so too will a Christian who is in favor of helping the needy do whatever he can to "demand that the government" help the needy.
Of course, we both know that your term "demand that the government" do whatever is just exaggeration because you want to make it sound like it's some big scary socialist boogeyman. In the case of abortion or helping the needy through socialist programs nobody can "demand that the government" do anything. We can only take part in the democratic process and hope that our efforts result in what we want our government to do.
So do you have the same approach about abortions, or drugs, or prostitution, or any other things we have laws about, i.e. that no Christian should use their Christian beliefs as a basis to support in our democratic process a law or initiative that is in line with their beliefs, because the Bible doesn't say "thou shalt demand that the government do that which I have commanded you"???
Here’s the point: he who plants sparingly also harvests sparingly.Each should give according to what he has decided in his heart, not grudgingly or under compulsion, for God loves a cheerful giver.Moreover, God has the power to provide you with every gracious gift in abundance, so that always in every way you will have all you need yourselves and be able to provide abundantly for every good cause — - 2 Corinthians 9:6-8
Bible Gateway passage: 2 Corinthians 9:6-8 - Complete Jewish Bible
So this passage means don't worry about giving to the needy, poor, sick, children, elderly because if they plant sparingly they must then harvest sparingly? And because God has the power to provide them with every gracious gift in abundance so we never should give to those in need because of this?
These are the excuses people make and the ways they cherry pick from the Bible while ignoring other verses that command us to give to the needy. Sorry, I don't buy it when God's Word is so abundantly clear that it is our duty to help those in need.
Those who make the same arguments you make fail to make the connection between justice and mercy which is at the heart of the Gospel and God's Word. We are taught that the wages of sin is death and that he who plants sparingly also harvests sparingly. We are taught in the same Bible that by God's mercy we are saved from death (which is the rightful result of our sin) and it teaches that the needy ought to be helped so that they harvest more than they have planted because we ought to show God's mercy in what we do.
Bottom line is that money shouldn't be so important to a Christian that they would be so cheap so as to want people to suffer so that they can save a few bucks and that's what people are doing when they don't support government initiatives to help the needy. That's the point of money-worship.
Do you truly believe that God has the power to provide you with every gracious gift in abundance, so that always in every way you will have? I do. That's why I am happy to advocate and support laws and economic policies that support the needy with money from my taxes. Because money is not the be-all end-all in my life. God is who can deliver whatever I need. Money does not. I know that if the government takes more of my money and it is to help the needy then God will also take care of me without that money that I am "losing". It's not my money. It's not your money, either. It doesn't belong to any of the people who have it. So why are you so worried about the money when people who are in need can benefit from it? God will take care of you. Or do you have doubts about that???
