Homosexuality like other is a Sin, offcourse like other Sin, Satan will try to take Advantage of that Sin, even in Christians, he Exalts such Emotions and Desires, like he would Tempt or Exalt a feeling or Desire of Lust, just for the Example. Homosexuallity is a Sin, as far as i Understand it, that if Satan is looking for to Tempt a Man who isnt Homosexual, he has nothing to work with in that man.
A Pasive Homosexual is like any other Person who Repents from any other Sin, and just like any man with any other Sin is able to be filled with any Spiritual Gift and Jesus Christ with the Holy Spirit.
Like any Other Sin, if you Sin you are in Bondage and just like any other Sin, if you are a Liar or like to look at a Women to lust after, the Holy Spirit although is still Present with us, will not be as Effective, Exalted as it should be.
If a Man is an Active Homosexual he can Repent, there is no issue about it, like a smoker or a thieve, someone with a Proud Heart and so on...and then again be Filled with the Holy Spirit in a great Measure.
Also, the Holy Spirit as i Believe is also active and convicting the Man who commits such Sins and will not Depart from him until the Grace of God will be pulled back. Remember were talking about Full of the Holy Spirit meaning 100%, i Hardly Believe that most of us or a great deal of us, although not Practicing Most Sins are really 100% Full of the Holy Spirit.
So yes i believe an Active Homosexual Christian can be filled with the Holy Spirit of some measure, therefor will be Convicted of his Sins and Repent, and yes i Believe there are Passive Gay Christians who are in a great deal filled with the Holy Spirit.
