Why does God "hate" homosexuality?
When we read in Genesis 1:28 we see God tell Adam and Eve to be fruitful ans multiply over the face of the earth, and to subdue it. We see the same being said to Noah in Genesis 9:1, 7. This is a command that extends though the generations of Humanity to this day. So why then is homosexuality out? Because it results in the deaths of entire bloodlines, no children can be produced from the union of a people of the same sex.
But what about infertile couples then, are they doomed as well? No! We get the answer to this question in Genesis 30:1-2 when Jacob answers Rachel saying, "am I in the place of God who has withheld from you you, the fruit of the womb. God is the one through whom all life is produced. There is no person alive today, unless God had a hand in their creation.
God is the author of life, and can use any life to further his Kingdom. But be aware, there is one tries his best to destroy God's great creation, and it seems as though he is doing a great job. Satan was a liar and a murder from the beginning. But he will not win, his goal is to drag as much of God's good creation to hell with him. Are we going to follow God or follow Satan? The choice in this yours.
Repent and believe the good news of the Gospel of Jesus the Christ. His kingdom is from everlasting to everlasting. He is the only righteous ruler, and judge of the nations. Repent, and seek his kingdom, or continue to let Satan rule over you and be dragged down with him.
Edit: this is my defense of why homosexuality is condemned in the Bible. This is not up for debate. This is my understanding, and many true followers of Christ would agree. It's not up for debate. Athiests and progressives need not comment. Thank you for your concern.
