Why is being gay supposed to be a "deal killer" when it comes to getting into heaven? Can a gay man be baptized and be
welcomed into heaven?
The reason some people think that being gay is a "deal killer" is because of the significance scripture gives on the subject of homosexuality. Because this one tends to 'stand out' more than other prohibitions, people tend to focus on this more than other sins. Also, because it goes against the natural order that God had planned for mankind. There are a number of verses in scripture that address homosexuality. One of the common ones that people will quote is in 1st. Corinthians chapter 6. Christians tend to always quote verses 9 and 10 which state;
"Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God." 1 Cor. 6: 9-10 (NKJV)
However, not to many people continue with the next verse, 11;
"And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God." 1 Cor. 6:11 (NKJV)
What this all means is that yes, homosexuality is a sin. Scripture says it's an abomination (Lev. 18:22). So are all of the other things mentioned in the above verses. but look at verse 11. Does this mean homosexuality can be forgiven? Even with all of the other verses in the Bible that speak of it? Yes! This and all of the things in these verses that Paul was speaking about can and will be forgiven if one repents from them (Turn away from them). Only in intentionally doing these things, especially after coming to know what God expects of us will keep you from entering the Kingdom of Heaven. Homosexuality is a choice!
As Christians, we are to be compassionate towards anyone who is sinning, but we are not to be tolerant of the sin. We are all sinners. There is a difference between hating the act compared to hating the person.
