Are GLBT churches legit?

Nope, afraid not. The Bible mentions same-sex relations in many places and none of these mentions condone this practice. For example Leviticus 18:22:

Do not have sexual relations with a man as one does with a woman; that is detestable.

Many GLBT people just assume that statements like this are outdated. Those GLBT people who believe in God will just say "God made me this way". There is nothing in the Bible that's outdated and there is no 'gay gene'. There is a statement "God loves the sinner, but hates the sin". This is found nowhere in the Bible and was probably planted by Satan.

Is this sin unforgiveable? No but it's very difficult for most GLBT people. First they have to recognize it as a sin and repent for it. Then they have to stop sinning. A tall order for most GLBT folks.
