Let me pose some questions:
Can a Christian be a murderer?
Can a Christian steal?
Can a Christian be an adulterer?
Can a Christian be a liar?
The answer is certainly YES!
But what does that solve. It is shallow, because it does not ask the real question... though it might suggest it.
"To be gay" is to have sex with someone of the same sex, to choose to be sexually active with someone and have a relationship with this person in the most intimate way possible.
The Bible says the two shall become one, meaning obviously one man and one woman.
The physical sexual organs of the male and female body align (fit) most naturally together. A simpleton can clearly tell that this is not so for two woman or two men, having like sexual organs they cannot naturally complete each other in a physical, sexual manner.
Now I am not naive, I know the two same sex people find many ways of sexually gratifying each other but the obvious point is two same sex people will never join together as God intended as a perfect match (one having what the other does not) and thereby most naturally become one together.
Can a person have sex with an animal? Is that natural? Can two males or females have sex with each other? Is that natural?
And what do I mean by natural? according to nature, by design, created to be that way.
So beyond the physical, "Can a Christian be a Gay", or simply be Gay (living the gay lifestyle)?
A Christian is humanly possible to do anything a non-Christian can do. Are they not? So, we are not talking about physically... we are talking about by definition.
What is a Christian? A person who has CHOSEN to follow Christ. A follower of Christ by grace accepts Jesus' death in place of their own as a sacrifice and payment due of their own life owed to God for sin. You see, many people do not understand what it means to be a Christian. Choosing to be a Christian means that a person has chosen to follow the Bible, Its teachings, to the very best of their ability and most importantly with the aid of the power of the Holy Spirit to help them understand what it says.
I can say many things but that does not make me many things.
I can say I am a vegetarian, but if I eat a nice thick steak am I a vegetarian?
What makes a person a vegetarian? It is a person who eat vegetables and no meat to varying degrees. I have never known of a vegetarian who eats steak. It is kind of like eating steak disqualifies a person from being a vegetarian because this person is not following the rules or description of what it means to be a vegetarian. A person who openly and continually eats meat is not a true vegetarian.
The Bible is clear on the fact that homosexual relationships are not to be followed by Christians, and that it is a sin against God. All Christians sin but any person that openly continues in a lifestyle of clear sin not repentant or surrendering to the power of the Holy Spirit to be transformed into the likeness of Jesus Christ... well that person is not a true Christian.
I don't think this is too hard to follow or understand. I hope this helps to answer this question that many have.
Let me end with this:
a friend of mine just last week shared that her pastor said the question is not "is a person once saved, always saved", it is "IF a person is once saved, then they are always saved". Thus related to this topic, IF a person is a Christian, they are always a Christian... thus a Christian could never live a life in continual repetitive sin and not be led by the Holy Spirit to be changed and to repent of that sin... regardless of what sin it is.
Lots of Love,
