I don't think it's necessarily a way we should care for the poor, so much as a way we can care for the poor. What the commandments against stealing and covetousness have to do with that is something that you'll have to explain.
It should be readily apparent what 'thou shalt not covet' and 'thou shalt not steal' have to do with forceably taking the bread of one man's labor to give to another man. This is ELEMENTARY David.
As for your idea that "put not your trust in princes" relates to government, I think that may be a case of you adhering to what you wish God said as opposed to what he actually said.
I've actually done an in depth study of God's commands regarding governmment, kings and princes and yes, God gives government very little responsiblity, the two primary things being wielding the sword against the evil doers and ensuring justice is done (as God defines it, not as men have redefined it).
Paul tells us "Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God," and given that the governments in the UK and the US are a lot better than the one in Rome in Paul's time, I think we can feel a lot better submitting ourselves to the governing authorities than people to whom Paul was writing could.
And God's throne for men is established in righteousness and those He appoints to lead answer to Him for their handling of the duties He gives them. Yes, as Christians we submit to the governing authorities and their laws (unless they require that we do something that would cause us to disobey God, in which case do NOT obey them). Obviously a great many kings and princes have utterly ignored their duties to God (Hitler, Stalin, Pol Pot, Idi Amin to name just a few) and used their positions of power for their own purposes.
As for same-sex marriage, given that the government (in the UK at least, not 100% sure how it works in the US) is responsible for legislating marriage
In the U.S. the Federal government has no Constitutional authority to involve itself in defining marriage so such determinations should be left to the states.
then it's up to them whether or not to okay same-sex marriage.
No government, having been instituted by God and answering to Him, can properly legalize 'gay marriage' when God has made marriage between a man and a woman. Some governments are of course 'legalizing' gay marriage though I don't see what that gains same sex couples. Government recognition of their unions will avail them nothing when they appear before Jesus to answer to Him for their disobedience.
It's got nothing to do "a man shall not lay with a man as with a woman," 'cos even if that verse is specifically referring to sex (contextually unlikely)
The Bible clearly condemns same sex sexual relations in both the OT and NT. That you think it is 'contextually unlikely' I find baffling considering that is the clear meaning of all scripture that addresses same sex relations.
the reality is that if two people want to have sex together they will, regardless of whether or not they're married.
David.
That is one of the marvelous aspects of salvation through Jesus. God will change us so we don't remain subject to the domination of the lusts of the flesh such as fornication or coveting the property of our neighbor etc. That so many people do choose the lusts of the flesh over the holiness that God calls us to simply reveals how fallen we are.
David, I hope you understand that God will typically not stop people who are determined to ruin themselves. He has called us to Him but those who don't want Him will be left to the misery their sins bring them and His ultimate judgment, wrath and destruction of them. That this is true one just needs to look at modern society with its rampant fornication, gays pairing off, murder, abortion, theft and so forth. God doesn't warn us about sin to keep us from having joy or pleasure in our lives, He warns us about sin because it does great harm to us in this life and will separate us from Him in the next.
