Hi Sree,
I will try to make my reply easier by breaking up your comment into segments and addressing each separately:
"So you agree with science that Homosexuality is genetic?"
Science is an important tool that God has given us to better understand Him and all that He has made. And although I don't agree with every conclusion made by different scientists, science itself is not contradictory to faith but rather strengthens and upholds it. It is our godless culture that has created a false dichotomy between faith and science which has unfortunately been working toward their favor, especially as many Christians have fallen victim to said lie and try to run the complete opposite direction, practically shunning knowledge. This is one of the many reasons why we as Christians are labelled as "ignorant" today. They have set the bait and we have taken it in the sense that they try to argue about genetic predisposition as a means to legitimatize homosexuality and we get hung up on that instead of getting to the root, by making them understand that genetic predisposition doesn't matter because we are all predisposed to SIN and are called to turn from our carnal (natural) self toward Christ and live.
And as I mentioned, I believe that homosexuality can be a result of nature, nurture, or both in a variable degree from person to person, so to answer your question, I agree with science that people can have a genetic disposition to make them more likely to be led to a homosexual lifestyle than another person but I do not agree that this sets a precedence to say that homosexuality is acceptable which is a false conclusion made from the studies.
"But you want believers to rebuke them and make them carry the cross, there by asking them to be attracted to women which is not a natural thing for them? Or you want them to remain single?"
To answer this question, I will start with a question: if you know of a brother or sister who is struggling (the key word here) with alcohol, will you continually rebuke them every time they fall and just leave it at that or will you try to bear with them their burden and demonstrate patience and kindness and show in a clear way that you actually care about them as a person and want them desperately to be set free from their bondage and remind them of the grace we have through the gospel of Jesus Christ? I don't know about you, but I struggle with a lot of things myself, and there have been times when people around me showed me such grace and spoke truth (the gospel) into my life which has helped me to overcome different sins. Remember, at the end of the day, homosexuality is a sin just like the sins you and I commit on a daily basis. Also, it is scientifically proven that babies can be born with addiction to different substances if their mother happened to use those substances during pregnancy, which can also manifest itself later on in life after a period of dormancy. I will address the last part of your question of this section at the end of my reply.
"I am just trying to understand your point, I always believed Homosexuality is a situational thing due to wrong upbringing of Child. It cannot be genetics no matter how Science tries to prove. I have placed my arguments in my previous post."
How can you be so certain that homosexuality cannot have a genetic component to it? Do you have biblical evidence to support this claim? We actually see a greater precedence for a genetic basis of sin in general from the fall of man and the idea of sin dwelling in our flesh. As far as I know, ever single human being is predisposed to sin and sinfulness is not something that is taught, it is just something that we are. Even King David says "I was sinful from birth." But an important point to make here is that we are not born committing every single sin there is known to man or will every single person commit every single sin there is to commit in their lifetime. Where am I going with this statement? To point out that every person struggles with different sins, even from their childhood, some being more prone to anger and rebellion to their parents than others, some more prone to steal and hurt other kids, while some are more mild and gentle. To me, it doesn't take much of a logical jump from here to say that some kids can also be more prone to homosexuality than others based on the reasoning stated above.
"I agree with you about fallen human nature like lies etc. But Homosexuality is different from lies, one can take the cross and speak the truth, but one cannot take the cross and act like he is sexually interested in a women when he is not."
Once again, I am not sure how you are coming to make such a strong distinction between homosexuality and all other sins. Are not all sins lies at the core?
Let me use an example utilizing the logic that you presented here (or at least what I understand from what you have written above, which wasn't all to clear to me): A boy struggles with lust and is "inflamed with passion" for girls, not just one, but almost every pretty girls he sees, it is his nature to do so. Now, is he unsaved because he has these super strong desires that he struggles with, as in he knows the thoughts are not pleasing to the Lord and he also desires to be free from them? Or let me use another example: I heard that married men to varying degrees struggle with unfaithful thoughts and desires and even moments where they have a sexual image in their mind that is not of their wife and that this is something that they struggle with for a long time. Are these men not saved because they struggle with such thoughts?
God sometimes seems to quickly bring deliverance from certain sins while allowing us to struggle with others while another person might have the very opposite happen where what you struggle with was more easily overcome by the other person while they struggle with something you easily overcame. Just as I know that I will probably struggle with lust for a long time but have no temptation toward homosexuality, I don't find it hard to believe that another person might not have much difficulty in regard to lust but have a great deal of difficulty in regards to homosexuality.
So at the end of the day, the point is not about arguing with the secular world if people can be born a homosexual or not and appearing ignorant by so easily brushing off any sort of scientific data saying "I don't believe in science", but getting to the more relevant argument that we are ALL born sinners and that gossip and slander and lust and rebellion against parents is just as much a damnable sin as homosexuality. And since we are all sinners from birth, we must deny our sinful impulses aroused by the flesh, and submit to God through Christ, and live.
