Homosexuality is a sin?

1.  GOD states that it is a sin. GOD should decide what is right and wrong, His degrees on are Eternal unlike man's degrees that have changed constantly throughout history. 
2.  After someone is Born Again, they lose desire to be a homosexual as they do with every other sin including un-forgiveness, lust, fornication, drug use and abusive language. (Click here to watch ex-homosexuals who were set free by GOD's power.) 
3.  Because the bond between a male and a female in marriage is sacred and from GOD, these union eventually produces children. Children are a blessing from GOD, and if GOD's perfect will was homosexual relationships He wouldn't have commanded against it and He would have made that union sacred, child bearing and state that in His Word (Instead of doing the opposite of all three.)
4.  Children are best raised with a husband and a wife, there two qualities help their children grow and develop and understand sexuality Biblically.
