Okay, I’m going to tackle this rapidly increasing issue of 21st century America. Unfortunately, this issue has risen to high promenance, and most non-Christians believe in it. I’m going to give a few Bible-based reasons on why no Bible-believing Christian man or woman can support this idea.
My first reason is that it explicitly contradicts the Bible. Leviticus 18:22 says “You shall not lie with a male as with a woman, it is an abomination.” In Leviticus 20:13, God decrees “If a man lies with a male as with a woman, both of them have committed an abomination; they shall surely be put to death; their blood is upon them.” We can thus conclude that it is against the Bible to even engage in homosexual behavior, whether male or female, not even to mention homosexual marriage. In Romans 1:24-31, Paul uses homosexual behavior to show that “God gave them up in the lusts of their hearts to impurity….” Thus, we conclude, homosexuality is sexual immorality.
In 1 Corinthians 6:12, Paul tells us that “The body is not meant for sexual immorality, but for the Lord, and the Lord for the body.” Thus we can say, since homosexuality is sexual immorality, that homosexuality is not meant for the body. In verse 19, Paul says “Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own.” Since homosexuality is not meant for the body, which is the temple of the Holy Spirit within us, we can say that homosexuality is not permitted by the Holy Spirit, the Spirit being one part of the Trinity, along with the Father and the Son, we can thus conclude that homosexuality is not permitted by God.
Since sin is also not permitted by God, we can then conclude that homosexuality is a sin. In Romans 6:23, Paul tells us that “The wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” Thus, homosexuality will lead to death. Now we can say that, based on Revelation 20:14-15, that those names not found in the book of life will be thrown in the lake of fire, along with Death and Hades. Thus we have that, since homosexuality leads to death, and death will be cast into the lake of fire, that those who practice homosexuality will be thrown into the lake of fire.
In summary: homosexuality is sexual immorality that is explicitly condemned in the Bible. Sexual immorality is a sin, and sin leads to death, therefore, homosexuality leads to death. Death will be cast into the lake of fire, and thus we can conclude that, since homosexuality leads to death, that those who practice homosexuality will be cast into the lake of fire.
