1. Take care of the poor: "If there is a poor man among your brothers in any of the towns of the land that the LORD your God is giving you, do not be hardhearted or tightfisted toward your poor brother." Deuteronomy 15:7. See also: Deuteronomy 15:7, Leviticus 25:25, 35, 39, Deuteronomy 24:19-21, Proverbs 21:13, Proverbs 19:17, Proverbs 14:13, Isaiah 58:6-7, Matthew 19:21, Matthew 25:3 -- to name a small handful.
2. Fight for justice for the poor: "Do not deny justice to your poor people in their lawsuits." Exodus 23:6. See also:
3. Pay your tithe: "Will a man rob God? Yet you rob me. "But you ask, 'How do we rob you?' "In tithes and offerings." Malachi 3:8. See also Leviticus 27:30; Numbers 18:26; Deuteronomy 14:24; 2 Chronicles 31:5.
4. Don't judge others, hold a grudge against them, or become angry with them: "Judge not, and you will not be judged; condemn not, and you will not be condemned; forgive, and you will be forgiven." Luke 6:37. See also Romans 14:12-13, Matthew 7:1-5, 1 Corinthians 1:5, Matthew 5:2.
5. Focus on God, not accomplishments, money or power: "For all that is in the world—the desires of the flesh and the desires of
the eyes and pride in possessions—is not from the Father but is from
the world."1 John 2:16. See also Luke 9:25, Matthew 6:33, 1 Timothy 6:9, Philippians 2:4, Matthew 23:12, Colossians 2:8, Luke 22:26, Isaiah 5:8.
There's nothing in the Bible about gay marriage. Monogamous gay relationships are not addressed in the Bible; the original words in Leviticus, Romans, etc, all connote non-monogamous relationships with prostitutes or young boys, or as parts of orgies.
Beyond that, though, political actions to deprive gay people of civil rights in the interest of
1. saving their souls, somehow or
2. "preserving the sanctity of marriage"
1. counterproductive: you can't bully someone into agreeing with you,
2. inconsistent: we're not regulating remarriage or adultery, last I checked, and
3. hateful, sanctimonious garbage: if your marriage is so unstable that the existence of gay married couples threatens it, then you need to be tending your own garden.
I am really, really, really angry that people are using Christianity as a rhetorical tactic in promoting their own agendas. Jesus said nothing about being gay, or about any obligation of Christians to impose even the most inarguable moral agenda on others. He said to come to Him. He said He was the way.
How weak does your faith have to be in order to believe that, should Jesus have a problem with the way someone is living, He needs you to seek them out to tell them?
That is not the gospel we're supposed to be sharing; anyone who has read the Gospel has to concede that. And don't quote the 2 or 3 passages that address going to "your brother" and addressing his sin. You're wasting time that could be spent sharing God with others on something totally meaningless and not your business; you haven't earned the right to call any of these gay people who you're apparently dead-set on regulating into Heaven you brother.
I've met one Christian who can point to one chapter of the Bible that she states supports her beliefs about homosexuality (I don't agree, but I give her credit for substantiating her belief with something other than blind hate). Christians who have chosen this issue as needing government regulation need to have the guts to acknowledge that they are editing out the entire Gospel, which is extremely clear about what Christ calls us to do, and which does not mention homosexuality at any point. It does, however, have much to say about people who interfere with others' access to Jesus -- say, by snatching away from Caesar what is his and claiming Jesus made you do it.
