As we think about sharing the gospel with LGBT people let us remember that they are people too. Every one of us is a sinner and every sinner needs Christ. The biggest need of every homosexual, is Christ. No matter how you share the gospel, do your best to keep the focus on Christ. There will be many distractions and many questions but we must always bring it back to Christ, the truth of who he is, and what he has done for us. 

1 Corinthians 1:17 For Christ did not send me to baptize, but to preach the gospel--not with wisdom and eloquence, lest the cross of Christ be emptied of its power.
We can also say that the most important thing Christ has called us to do is to share the gospel of Christ and the cross. Let’s not make it too complicated, let’s be loving, let’s be clear, and let’s share the gospel.
Remember homosexuals didn’t start the LGBT movement.
In the US the foundation for the LGBT movement was not laid by homosexuals but rather mainly by heterosexual Christians.
“Today’s movement toward the total acceptance of homosexual behavior and relationships was only made possible because some heterosexuals first did their best to undermine marriage.”

Dr. Albert Mohler “We Can’t Be Silent”
Dr. Albert Mohler explains in his book that the sexual revolution began by the destruction of marriage and the biblical meaning of family. 
“Heterosexuals did a very good job of undermining marriage before the culture forces began advocating for the normalization of same-sex relationships and the legalization of same-sex marriage. The marriage crisis is a moral crisis that did not start with same-sex marriage, nor will it end there. The logic of same-sex marriage cannot end with same-sex marriage. Once marriage can mean anything other than a heterosexual union, it can and must eventually mean everything”

Dr. Albert Mohler “We Can’t Be Silent”
We must admit the guilt of many heterosexuals who destroyed families through divorce, adultery, and sexual sin. This is what laid the foundation for the LGBT movement today. They are simply continuing what we started. As we admit our guilt it changes our attitude and approach towards the LGBT community. Rather than making this an “Us vs them” battle, we realize that we as heterosexuals are not without guilt. Thus any conversation we have with the LGBT community must began not began with a finger pointed at them but rather with the pronoun “we”
For all have sinned and fall short of the glory of God. Romans 3:23
Humility is vital when we approach anyone with the gospel but when we share the gospel with the LGBT community it is even more vital. Why? Because often there is already the assumption by the LGBT community that we are pointing our finger down upon them. We must have the humility to show them that we are all sinners before God. 
1 Timothy 1:15 Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners--of whom I am the worst.
I must recognize my sin as “worse” than their sin. This is the attitude we must have when we share the gospel. We recognize our own sin as worse because we are intimately connected with our own sin. Because we see and feel the effects of our own sin. Because we know the secret sins of our heart that only God and I can see! This attitude must permeate our hearts when we share the gospel. It will often be through simple humility, openness, and service that we will win the opportunity to speak with someone about Christ. Without this humility our efforts to share the gospel will look more like someone trying to expose another’s sin and shame them before the public.

Let them know that you also struggle with sin, even sexual sin. Speak to them as a sinner who found grace in Jesus not as a finger-pointing preacher whose only remaining sin is being too long-winded on Sunday mornings!
