“show me where this “method” charity has to be earned or paid back according to the bible. “
If a man is unwilling to work he should starve. Interesting that you support the welfare mentality.
A "man unwilling to work" isn't a charity case now is he. BTW, cite your bible - if you have one because I don't think you've cited it correctly.
We are told to take care of the widow and the fatherless - no reference to having to make them 'work' for it. Further, there is nothing requiring "work" for taking care of "the least of these" (MT:25) Romans 15 cites a collection for the poor in Jerusalem - no strings attached.
The fact of the matter is the context of 2 Thess 3:10 (there saved you from having to look it up - but try it anyway, good for the soul) reflect on freeloading, and not those in need. Those in need should do what they can to better their situation, and the church should help. But if those individuals think that charity/welfare is something owed to them - then they should work (scripture kicks in).
As for "welfare mentality", far be it. "Welfare mentality" includes forced taxation and the recipient demanding services as if it was a right. You would be hard pressed to make such a judgement stick.
Bottom line is that charity is appropriate to those who's circumstances out of their control affect their ability to support their family. That is the overall gist of those who should receive charity. Those who's circumstances are self-generated should receive some help provided they are correcting their lives. Those who demand charity and think it a right should not receive it. That's not welfare, thats scripture guidances.
