One question: what exactly is a "homosexual lifestyle," considering the fact that not all homosexuals have sex and that homosexuals live the exact same sort of life as heterosexuals do?
Ok that's a great question. I suppose it would be necessary to define terminology as it is very possible that everyone attributes a different meaning to the key words we are using.
In my opinion and in my definition:
Homosexuality: Describes a person with same sex attraction who has decided to openly embrace the gay life style of having sexual relations with the same sex.
Same Sex Attraction: A person who has an attraction to the same sex, yet chooses not to act on those desires.
I believe that the character of scripture when It describes homosexuality, is describing people who actively embrace and participate in homosexual behavior as a lifestyle and a sexuality option.
I understand that there are people who are attracted to the same sex, yet do not embrace homosexuality as a viable option and recognize that calls God homosexual sex sin.
The whole point I have been attempting to make here, is that homosexuals essentially claim that because they feel attraction to the same sex, then that means God made them that way and that they have the right to act on those desires.
If we use this logic, then a pedophile is also justified in molesting children, because he is attracted to children; a cumpulsive gambler can claim that he was born with the desire to gamble, therefore, he is justified in gambling.
As a side note, when you explore the homosexual topic, there is overwhelming amounts of evidence that suggest same sex attraction is brought on in very early childhood due to several external factors that cause a person to be attracted to the same sex and it become sexualized.
When a person says "I am a gay christian" and by this they mean that I am a christian and I openly embrace the gay lifestyle of having sexual relations with the same sex, then this is at odds with the teaching of scripture. One cannot be a christian and openly embrace and live sinful lifestyle regardless of what that sin is. This is rebellion toward God.
1 John 3:4-10
4 Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness. 5 You know that he appeared to take away sins, and in him there is no sin. 6 No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. 7 Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous. 8 Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil. 9 No one born of God makes a practice of sinning, for God's seed abides in him, and he cannot keep on sinning because he has been born of God. 10 By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.
When a person says, I am a gay christian" and by this they mean that I have same sex attractions, yet I recognize that having sexual relations with the same sex is sin in God's eyes; therefore, I yield this to God and look to him for grace to overcome the temptation and find freedom from it. Then this view is not at odds with scripture, although I don't think "I am a gay christian" is the best description, because it denotes that a person has identified themselves as gay.
